This plot
This plot monitors the persistence in both IFS dark and IFS background calibrations
which can be generated by previously acquired IFS optical distortion calibrations.
These optical distortion calibrations can leave a pinhole slice pattern in the IFS dark or background pipeline product.
The QC parameter is simply: the median counts in the pipeline product in a window P = [770, 1300 --- 850, 1440]
minus the median counts in window B = [640, 1470 --- 720, 1570].
Window P (pinhole) is the area where the pinhole slice pattern can show up and window B (background) is the area
off the pinhole slice pattern areas on the detector.
This kind of monitoring was introduced 2018-01-01.
IFS_DARK master frames are not used to calibrate observations, only
the ancillary IFS_DARK product IFS_STATIC_BADPIXEL is used. IFS_BACK
calibrations are used to calibrate science observations.
General information
Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot.
If configured,
- data points belonging to the latest date are specially marked
- statistical averages are indicated by a solid line, and thresholds by broken lines
- outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
- "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
