master:
- obspy.core:
* Fixed import of custom plugins (see #2423)
* Fixed "==" comparison for Stream and Trace which was very slow in case of
traces with >1e6 samples (see #2377)
* Added almost_equal method for Stream and Trace classes (see #2286).
* Casting FDSN identifiers to strings upon setting in the stats dictionary
(see #1997).
* UTCDateTime objects will now always evaluate equal if their string
representations are equal (see #2049).
* UTCDateTime objects now issue depreciation warnings when setting any
attributes outside of init, or comparing UTCDateTime objects with
different precisions (see #2077).
* UTCDateTime objects can now accept hour, minute, second, and microsecond
values greater than their normal limits by setting the strict keyword
argument to False (see #2232).
* Added replace method to UTCDateTime class (see #2077).
* Added remove method to Inventory class (see #2088).
* Added id property to WaveformStreamID (see #2131).
* Added __str__ and _repr_pretty_ method for Comment class (see #2115)
* Added __eq__ to QuantityError so empty instances equal None (see #2185).
* Reworked the event scoped resource identifiers for the event classes
hopefully fixing all edge-cases (see #2091).
* Added a hook to allow users to customize finding objects for
resource_ids which are not found via the normal means (see #2279).
* Calling Stream.write(...) on an empty stream will now raise an
ObsPyException consistently across all I/O plugins (see #2201)
* Stream.get_gaps() will now properly report gaps within Traces that
have masked arrays (i.e. Traces that have been merged without a fill
value, see #2299 and #2300).
* Added copy method to Inventory class (see #2322).
* The Response.recalculate_overall_sensitivity() method now accepts integers
(see #2338, #2343).
* Added wildcard and url support to read_inventory (see #2326).
* Modified stream.get_gaps() to deal with overlaps correctly (see #1403)
* Added option "label_epoch_dates" to Inventory/Network.plot_response() to
optionally add channel epoch start/end dates to legend labels (see #2309)
* Deprecated the convert_id_to_quakeml_uri, regenerate_uuid, and
get_quakeml_uri methods of the ResourceIdentifier class (see #2303).
* Added get_quakeml_uri_str and get_quakeml_id methods to the
ResourceIdentifier class (see #2303).
- obspy.clients.fdsn:
* Add new `_discover_services` boolean flag to the Client, which allows the
Client to skip the initial services query at instantiation. This can
reduce the load on service providers, but skips checks against unsupported
query parameters.
* Adding more location codes to the default priority list in the mass
downloader (see #2155, #2159).
* The mass downloader now raises a warning if all channels from a station
have been deselected due to the default location priorities setting. This
is a pure usability improvement as it has been confusing users
(see #2159).
* make sure that streams fetched via FDSN are properly trimmed to user
requested times if data center serves additional data around the start/end
(see #1887, #2298)
* fix a problem that could spam subprocesses that were not closed in routed
clients (see #2342 and #2344)
* make it possible to use signed EIDA tokens and also skip token validation
completely (see #2297)
- obspy.clients.seishub:
* Properly handle fetching poles and zeros in presence of multiple metadata
files for a given station (see #2411)
- obspy.imaging:
* obspy-scan can now be used with wildcarded SEED IDs when specifying what
to plot after scanning data (see #2227)
* fix a problem in Scanner when loading npz on Python3 that was written on
Python2 (see #2413)
- obspy.io.mseed:
* The recordanalyzer can now detect calibration blockettes 300, 310,
and 320 (see #2370).
- obspy.io.nordic:
* Add ability to read and write focal mechanisms and moment tensor
information. (see #1924)
* Add explicit warnings regarding unsupported sections of Nordic files.
* Fix mapping of magnitude-types between MS to S and Ms to s.
* Output preferred origin when writing to Nordic format instead of using
the first origin (see #2195)
* Include high-accuracy phase-pick reading and writing - high-accuracy is
now the default phase-writing format, a boolean flag `high_accuracy`
has been added to turn this off. (see #2351 and #2348)
* Allow long-phase names (both reading and writing) - longer than 4 char.
(see #2351)
* Include AIN as takeoff-angle when reading and writing nordic files
(see #2404).
- obspy.io.reftek:
* Implement reading reftek encodings '16' and '32' (uncompressed data,
16/32bit integers, see #2058 and #2059)
- obspy.io.rg16:
* implement module to read waveforms and headers from fcnt format (see #2265).
- obspy.io.seg2:
* Handle data format code 3 trace data (#2022, #2385).
* Improve parsing of free-form entries (#2385).
* Fix non-native endian data loading (#2385).
- obspy.io.quakeml:
* Allow writing invalid ids but raise a warning
(see #2104, #2090, #2093, #1872).
* Skip invalid enumeration values during reading but raise a warning.
(see #2106, #2098, #2095)
* Catalogs with empty event description objects can be round-tripped (see
#2339, #2340).
- obspy.io.sac:
* Fix bug writing inventory with SOH channels to SACPZ (see #2200).
- obspy.io.segy:
* Raise nicer error messages when header packing fails (see #2194, #2196).
- obspy.io.seiscomp:
* Adding support for SC3ML 0.10 (see #2024).
* Update xsl to allow conversion of amplitude picks not associated with
origins (see #2273).
- obspy.io.sh:
* Add read support for SeismicHandler EVT event files (see #2109)
- obspy.io.shapefile:
* Add possibility to add custom database columns when writing catalog or
inventory objects to shapefile (see #2012 and #2305)
- obspy.io.xseed:
* Ability to parse SEED files with extra newlines between blockettes
(see #2383)
- obspy.io
* added read support for receiver gather format v. 1.6 (see #2070)
* added read support for FOCMEC 'out' and 'lst' files (see #2156)
* added read support for HypoDD 'pha' files (see #2378)
- obspy.signal.trigger:
* fix a bug in AR picker (see #2157)
* option to return Baer-Kradolfer characteristic function from pk_mbaer
function added (see #2341)
- obspy.signal.polarization:
* Fix an issue in selecting Z/N/E traces from given stream (see #2365)
- obspy.signal.PPSD:
* Fixed exact trace cutting for PSD segments (see #2040).
* Timestamp representations internally and in npz I/O were changed to use
integer nanosecond POSIX timestamps to avoid any potential floating point
inaccuracies and since this is also what UTCDateTime is based on nowadays
(see #2045)
* Fixed the check for new PSD slices whether they should be added or whether
they would add unwanted duplicated data (see #2229)
* Fix `period_lim` option when `xaxis_frequency=True` (see #2246)
- obspy.signal.cross_correlation:
* Add new `correlate_template()` function with 'full' normalization option,

* Azimuth is appended to arrivals as well (see #1289)
* Fixed issue with taup cache function on Python 2.7. (see #1308)
1.0.0: (doi: 10.5281/zenodo.46151)
- General:
* Requirements have been increased to reflect latest distributions:
* Removed support for Python 2.6.
* Added support for Python 3.5.
* matplotlib >= 1.1.0 is now required.
* numpy >= 1.6.1 is now required
* scipy >= 0.9.0 is now required
* Reorganized the submodule structure. We provide a deprecation path so the
old imports will continue to work for one ObsPy version.
* Consistent naming scheme across the code base. This results in some
functions having different names. Most things that worked with ObsPy 0.10
will continue to work with this version, but starting with the next
version they will fail. Pay attention to the deprecation warnings.
* Support for additional waveform data formats:
- Read support for the ASCII format for waveforms from the K-NET and
KiK-net strong-motion seismograph networks.
* Support for additional event data formats:
- CMTSOLUTION files used by many waveform solvers.
- ESRI shapefile write support, useful in GIS applications (see #1066)
- Google Earth KML output.
* Support for additional station data format:
- The FDSN web service station text format can now be read.
- Read support for the NIED's moment tensor TEXT format (see #1125)
- Google Earth KML output.
- Read support for SeisComP3 inventory files.
- obspy.core:
* New method for generating sliding windows from Stream/Trace windows.
(see #860)
* Stream/Trace.slice() now has the optional `nearest_sample` argument from
Stream/Trace.trim().
* Trace.remove_response() now has `plot` option to show/output a plot of all
individual steps of instrument response removal in frequency domain
(see #1116).
* New method Stream/Trace.remove_sensitivity() to remove instrument
sensitivity
* Fix incorrect parsing of some non-ISO8601 date/time strings. (see #1215)
* Added plotting method to Event (customizable subplots from a selection
of map, beachball and farfield radiation plots, see #1192)
- obspy.clients.fdsn:
* Replace FDSN webservice shortcut `NERIES` with `EMSC` and deprecate the
`NERIES` shortcut, will be removed in a future release (see #1146).
* Now requests gzipped data for the XML files. Much smaller files!
* The station service can now also be used to download files in the text
format. This has limited information but is much faster.
* New mass downloader to assist in downloading data across a large number
of FDSN web services.
* Catch invalid URLs when initialising Client and avoid confusing error
messages (see #1162)
- obspy.clients.filesystem.sds:
* New client to read data from local SDS directory structure (see #1135).
* Command line script `obspy-sds-report` to generate html page with
information on latency, data availability percentage and number of gaps
for a local SDS archive (see #1202)
- obspy.clients.neries:
* Removed the dedicated client. Data can still be accessed by using the FDSN
client.
- obspy.clients.syngine:
* New client for the IRIS Syngine service to retrieve custom synthetic
seismograms.
- obspy.imaging:
* Experimental support for Cartopy when plotting maps. Use the `method`
argument to functions that plot maps to select between Basemap or Cartopy.
* New default colormap for all plots. A backport of the new viridis colormap
from matplotlib is available for those using older matplotlib releases.
* Added plotting routines for farfield radiation patterns of moment tensors
- obspy.io.kml:
* New module for Google KML output of Inventory and Catalog objects
(e.g. for use in Google Earth)
- obspy.io.mseed:
* Upgrade to libmseed 2.16
- obspy.io.seiscomp.sc3ml:
* New module reading SeisComP3 inventory files to ObsPy inventory objects
(see #1182).
- obspy.io.shapefile:
* New module for ESRI shapefile write support (see #1066)
- obspy.io.stationtxt:
* New module reading the FDSN station files.
- obspy.signal:
* Switch to second-order sections for filters; backported from SciPy 0.16.0
(see #1028)
* New Lanczos interpolation/resampling (see #1101)
* Higher order detrending methods (see #1173)
* PPSD (see #931, #1108, #1130, #1187):
- Algorithm for PSD computation was improved, especially affecting results
at long periods (for detailed discussion see #931 and #1108).
- Keywords `paz` and `parser` were removed in favor of new keyword
`metadata`. PPSD now accepts `metadata` in a much wider range
of formats:
* Inventory objects (e.g. from StationXML or from FDSN webservice)
* obspy.io.xseed Parser objects (e.g. from dataless SEED file)
* filename of a RESP file
* dictionary with poles and zeros information (like in
prior versions)
Most old codes should still work, issuing a deprecation warning, but
old code that specifies *both* `paz` and `parser` keywords will raise
an exception.
- Whenever possible (i.e. when using for `metadata` an Inventory,
a Parser or a RESP file), response calculation now takes into account
the full response (all stages) as opposed to only using the poles and
zeros response stage (as was done in previous versions when using a
Parser object). When using a poles and zeros dictionary response
calculation is unchanged (as no information on other stages is
available, of course).
- PPSD now stores the psd for each time segment that gets processed,
instead of only storing the stacked histogram. That way, differing
custom stacks with various selection criteria (e.g. time of day, by
weekday, etc.) can now be made from the same processed data
(see #1130).
- New save/load mechanism using numpy .npz binary format that circumvents
some problems with the old pickle mechanism:
`PPSD.save_npz()` and `PPSD.load_npz()` (and `PPSD.add_npz()` to add
data from additional npz files)
- Change default colormap to new obspy default sequential colormap
(matplotlibs new viridis colormap). The old PQLX colormap is provided by
`obspy.imaging.cm.pqlx` and can be used with
`PPSD.plot(..., cmap=...)`.
- new option `PPSD.plot(..., cumulative=True)` for a cumulative plot of
the histogram, i.e. a non-exceedence percentage visualization, similar
to the `percentile` option.
- x axis in `PPSD.plot()` can be switched to frequency in Hz with
`PPSD.plot(..., xaxis_frequency=True)` (see #1130)
- changes to special handling of rotational: now handled by kwarg
`special_handling="ringlaser"` (kwarg `is_rotational_data` is
deprecated, see #916)
- special handling option for hydrophone data (no differentiation, see
#916)
- bin width on frequency axis can now be controlled using
`PPSD(..., frequency_bin_width_octaves=...)` (in fractions of octaves,
default is the old fixed setting of 1/8 octaves as in PQLX)
- obspy.taup
* Added support for nd file format for input velocity models. Allows for
named discontinuities at arbitrary depths allowing for less Earth like
models (see #1147).
* Added three methods (`get_travel_times_geo()`, `get_pierce_points_geo()`
and `get_ray_paths_geo()`) to `TauPyModel` to handle station and
event location data as latitude and longitude, instead of the source to
station distance in degrees. In addition `get_ray_paths_geo()` and
`get_pierce_points_geo()` decorate the returned pierce points and ray
paths with the latitude and longitude of each point. Some functionality
needs the `geographiclib` module to be installed. (See #1164.)
* ObsPy now ships with a bunch of new velocity models in addition to the
existing ones: `prem`, `sp6`, `1066a,b`, `herrin` (See #1196).
* Add support for buried receivers (see #1103.)
* Port more accurate calculation of ray parameter from Java. The effect is
stronger for longer phases, but also corrects issues with shorter body and
surface waves (see #986.)
* Fix incorrect branch splitting which also caused issues for extremely
shallow phases (see #1057.)
* Proper cache for model splits resulting in much faster calculations if
the source depth is repeatedly the same (see #1248).
0.10.3: (doi: 10.5281/zenodo.46150)
- obspy.core:
* Fix reading of multiple catalog files using globs (see #1065).
* Fixed a bug when using
`Trace.remove_response(..., water_level=None)`.
With that setting that is supposed to not use any water level
stabilization in the inversion of the instrument response
spectrum actually the instrument response was never inverted and
thus instead of a deconvolution a convolution was performed
(see #1104).
* Fixing floating point precision/rounding issue with UTCDateTime when
initializing with floating point seconds, i.e. with microseconds,
that could lead to microseconds being off by 1 microsecond
(see #1096)
* Correct gap/overlap time returned by Stream.get_gaps() and printed
by Stream.print_gaps() which was incorrect by one time the sampling
interval (see #1151)
* Stream.get_gaps(): return overlaps specified in units of samples
as negative integers (see #1151)
- obspy.fdsn:
* More detailed error messages on failing requests (see #1079)
* Follows redirects for POST requests (see #1143)
- obspy.imaging:
* fix some bugs in `obspy-scan` (see #1138)
- obspy.mseed:
* Blockette 100 is now only written for Traces that need it. Previously
it was written or not for all Traces, depending on whether the last
Trace needed it or not. (see #1069)
* Fixed a bug that prevented microsecond accuracy for times before 1970
(see #1102).
* Updated to libmseed 2.17.
- obspy.signal:
* Bug fixed within rotate.rotate2zne(). Additionally it can now also
perform the inverse rotation (see #1061).
* Bug fixed in triggering. When using option `max_len_delete` and a trigger
occurred right before the end of data, one trigger was potentially lost
(see #1145 for details).
- obspy.station:
* Plotting responses across multiple channels is more robust now in
presence of some strange channels (e.g. with zero sampling rate,
happens e.g. for state of health channels, see #1115)
* ObsPy no longer assumes that the StationXML namespace is the default
namespace (see #1060).
* Checking if a file is a StationXML file is less rigorous (and much
faster) now (not checking strict validity against xsd schema but
only looking for a FDSNStationXML root element, see #1114).
This means that `read_inventory()` without explicitly specified
format will correctly detect more files as StationXML that have very
slight breaches of the schema but still can be interpreted as
StationXML.
* fix saving `xcorrPickCorrection()` results to an image file (see #1154)
- obspy.taup:
* Calculating arrival times for surface waves now works (see #1055)
* Calculating arrivals for underside reflections now works (see #1089)
- obspy.y:
* correct misspelled name of a Y specific header field (see #1127)
- obspy.zmap
* Add support for time values with sub-second precision (see #1093)

* Basic seedlink client: Properly timeout requests with valid station
selection but no data available in selected time window (see #1045)
- obspy.signal:
* Fix return data types/values of polarization routines (see #1026)
- obspy.station:
* Fix URL to FDSN StationXML schema in StationXML output (see #1023)
