Fix Version/s: None
We would like to run Camera code and scripts regarding sensor characterization at NCSA.
The list of detector effects is long (c.f., https://confluence.lsstcorp.org/display/DM/Sensor+Characterization+and+ISR#/) but we can come up in this ticket with priorities (e..g, CTI correction, NL-crosstalk, bias instability, etc.) This ticket will serve as a parent ticket to other tickets related to this work.
We should identify the data that is needed (and if that data is already at NCSA), and the code/scripts needed to run it.
- is parent task of
DM-26468 Run Fe55 eotest analysis at NCSA
DM-26481 Run bright pixels eotest task at NCSA
DM-26484 Run read noise eotest task at NCSA
DM-26487 Run dark current eotest task at NCSA
DM-26516 Run (parallel and serial) CTE eotest task at NCSA
DM-26352 Run CTI correction code by A. Snyder et al. at NCSA
- is triggering
DM-26542 Run Camera Team crosstalk code at NCSA
- relates to
DM-26543 Calculate crosstalk coefficients from spot data using DM code

List of measurements to replicate:
- Serial CTI measurement and correction (Snyder+19, Snyder+20(in prep.): PUB-109):
- Crosstalk measurements: Adam Snyder is working on changing/improving their current xtalk algorithm; they will produce new analyses, so it is recommended to wait until then:
- Bias instabilities: Robert has been looking into this with recent BOT and ComCam data
- Fe55 analyses (e.g., gain):
- Read Noise
- Bright Pixels:
- Dark Current:
- Parallel, serial CTI:
- Blooming Full well
- Pixel Response Non-Uniformity
- Quantum Efficiency (ugrizy)
Just in case you're about to work on it, I just wanted to say I don't think the Quantum Efficiency (ugrizy) one is worth doing. There may be others, too, but that's the main one I'd drop.
Let's ticket the crosstalk work, even if we're not currently able to work on it. I'll do so.
From conversations with Jim Chiang: eotest was started around 2012, and the idea was to use the DM stack as much as possible. They ended up using mostly the low-level primitives.

On the CCP stand-up meeting today (https://confluence.lsstcorp.org/display/DM/2020-08-17+Calibration+Products+Standup), we agreed that the CTI correction work by Adam Snyder and colleagues at SLAC should be a priority (ticket:
DM-26352) Robert has been working recently on reproducing the analysts on bias stability by J. Chiang, S. Digel, A. Roodman, and others at SLAC on ComCam data (e.g., https://lsstc.slack.com/archives/CQ4SMS3QQ/p1596835699261700 and https://lsstc.slack.com/archives/CBV7K0DK6/p1597414740316900 ).
