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.
This parameter is determined from an overscan-subtracted calibration
lamp exposure in LSS mode (taken with the template
FORS2_lss_tec_flatLampcheck). The total signal is integrated and
normalized by the exposure time and the total number of original CCD
pixels (keeping into account possible binning). More information can
be found in the plot
tutorial.
The setup of the lamp check is G300V, GG435 and 1arcsec slit.
FFB12
Monitoring the lamp flux of the two
blue low brightness halogen lamps FlatBlue+1 and FlatBlue+2.
These lamps are used to generate imaging screen flats.
FFB34
Monitoring the lamp flux of the two
high brightness blue halogen lamps FlatBlue+3 and FlatBlue+4.
These lamps are used to generate spectroscopic flats in blue (G300V, G600B) spectroscopic setups.
FFR34
Monitoring the lamp flux of the two
red halogen lamps FlatRed+3 and FlatRed+4.
These lamps are used to generate spectroscopic flats in red spectroscopic setups.

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 ↓)
