Comment by Alicia Canipe on JIRA:
Just an update: we're trying to figure out why NGROUPS=1 didn't work for the PID 5398 observations when it did seem to work for other programs that have used NGROUPS=1:
Comment by Alicia Canipe on JIRA:
Tyler Pauly was obs 25 of 5398 the only one that had issues? Obs 27, 28, 25, 26 also all have NGROUPS=1 and the strange pattern, but it sounds like they made it though stage 3 okay?
Comment by Tyler Pauly on JIRA:
Obs 25 was the reported error from Ops, but I pulled o028 from MAST and tried image3, which failed for both LW and SW data. I'm guessing that 26 and 27 were not attempted because the direct image level 3 products were not generated.
Comment by Alicia Canipe on JIRA:
Okay thanks! That helps
Issue JP-3801 was created on JIRA by Tyler Pauly:
During operations processing of new data in jw05398, a pure parallel WFSS program, errors were returned during Level 3 processing of o025, a direct image component of the program observed with the setting NGROUPS=1.
The NIRCam team looked into it and reported that data taken with NGROUPS=1 can be subject to poor calibration; the data in question appear to have large bias residuals remaining during level 3 image processing, resulting in the outlier_detection step flagging all pixels as NaN/DO_NOT_USE.
