NOTE: The Health Check and calChecker services are moved to qcFlow on an instrument by instrument basis. The current pages will not be updated any longer once the move has been finished.
The links to KMOS, UVES, and ESPRESSO have been moved to a new section (qcFlow operational) at the lower part of the navigation bar.
The standard deviation over a sample of five raw frame maximum counts. This QC parameter is sensitive to fluctuations in the illumination level and/or to fluctuations of the jnumber of bad pixel.
Since 2018-03, VIS-arm flat frames are subject of fluctuations of the
illumination level within the sequence of five raw frames. One ore
more raw frames can show brighter flats than the remaing raw flats of the sequence.
Brighter instances of raw flats can be partially saturated.
The most sensitive QC parameter is the standard deviation of the raw
frame median counts (here plot (1) ).
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 ↓)
