Here we monitor the lamp flux in ADU/sec and the flat counts in ADU of the
daily acquired health check IFU flat
with setup 100k/1pt/hg. These HC IFU flats are composed of
two raw frames only, one with the D2 lamp and one with the QTH lamp.
The template is usually started twice a day, once at instrument startup and
once at the end of the day-time calibrations
The lamp flux is scored, the flat counts not.
There are
- deuterium halogen lamp flats (D2, used for lambda < 350 nm) operated with 4.667 sec exposure time and
- quartz lamp flats (QTH, used for lambda > 350 nm) operated with 12.333 sec exposure time .
Decrease in the D2/QTH flux might indicate problem with the UVB ADC.
For more information see the plot
tutorial page.

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
