 Unexpectedly, the dark current was significantly less in Run 7 than

 \subsubsection{Bright defects}\label{bright-defects}
 
 Bright defects are localized regions or individual pixels that produce abnormally high signal levels, even in the absence of light. These defects are typically caused by imperfections in the semiconductor material or manufacturing process of the CCD. Bright defects can manifest as ``hot pixels" with consistently high dark current, small clusters of pixels with elevated dark current, or as ``hot columns" (pixels along the same column that have high dark current).

 \subsubsection{Divisadero Tearing}
 
 Divisadero tearing (or Rabbit ears) is manifested as signal variations near amplifier boundaries, connected features that are often jagged \cite{2020arXiv200209439J,2024SPIE13103E..0WU}. These variations are on the order of \textasciitilde1\% relative to the flat field signal. To quantify divisadero tearing in a given column, we measure the column signal, and compare it to the mean column signal from flat fields.

 All camera performance metrics from the summit show close agreement with SLAC IR2 tests. PTC/full-well metrics were consistent, and no significant bright cosmetic defects developed. Dark cosmetic defects are difficult to quantify due to the edge sensor effects, though the consistency in CTI measurements would indicate that dark defects did not change from previous runs. Dark current and Divisadero tearing show improved performance compared to Run 6, while the Persistence feature is still prominent in e2v sensors.

The major change in the final camera operating conditions to combat persistence is decreased parallel swing. This change is applied to the e2v sensors only, as they are the subset of sensors that exhibit \geq 1 ADU persistence when using the Run 7 initial operating parameters.
