HENDRICS 8.0

• Compatible with Stingray 2.0.0, which introduced, among other things:

  • Lomb-Scargle periodograms and cross spectra are now available
  • Power colors
  • Easy filling of small gaps in light curves with random data
  • Generic timeseries (complex data, multi-dimensional data)

• HENaccelsearch now has additional options for detrending, denoising, and deorbiting

• An improved Maximum likelihood algorithm as FFTFIT substitute for TOA calculation

• NASA's IXPE added to supported missions

HENDRICS 8, first release candidate

• Compatible with Stingray
  2.0.0rc1,
  which introduced:

  • Lomb-Scargle periodograms and cross spectra are now available
  • Power colors
  • Easy filling of small gaps in light curves with random data
  • Generic timeseries (complex data, multi-dimensional data)

• HENaccelsearch now has additional options for detrending,
  denoising and deorbiting

• An improved Maximum likelihood algorithm as FFTFIT substitute for
  TOA calculation

• NASA's IXPE added to supported missions

• Better support of Stingray's native file formats

HENDRICS 7.0

• Based on Stingray 1.0, bringing a huge bump in performance
• Following Astropy, Numpy and Scipy, HENDRICS 7.0 is only compatible with Python >3.8
• Accepts many more file formats for round-trip of Stingray objects, thanks to the new functionality of Stingray.
• Energy-filtered periodograms
• A wider range of normalizations available for both HENfold and HENphaseogram, with more options (e.g. smoothing) and higher-contrast color map by default
• Many fixes to mission-specific files
• Better info returned by Z/EF searches, including pulse amplitude estimates
• New upper limit functionality in Z/EF searches with no candidates
• HENplot now estimates the error of frequency and frequency derivative searches returned by HENzsearch and HENefsearch with option --fast
• Add ability to split files at a given MJD

7.0b1: Merge pull request #139 from StingraySoftware/new_release

Fix bug #139

7.0 beta

• Based on Stingray 1.0, bringing a huge bump in performance
• Energy-filtered periodograms
• Many fixes to mission-specific files
• Better info returned by Z searches, including pulse amplitude estimates
• Add ability to split files at a given MJD
• New upper limit functionality in Z searches with no candidates

HENDRICS 6.0

HENDRICS 6.0 depends on Stingray >=0.3.
In this release, all the improvements from the Stingray release plus:

• Much improved mission support
