This plot
This plot monitors the persistence in 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 background pipeline product.
The QC parameter is simply: the median counts in the pipeline product in a window P = [770, 130 --- 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 2010-01-28.
IFS_DARK master frames are not used to calibrate science 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
