Here we monitor the lamp flux in ADU/sec and the flat counts in ADU of the      
daily acquired <b>health check</b> IFU flat.
These HC IFU flats are composed of
two raw frames only, one on-lamp and one off-lamp frame.
The template is usually started twice a day, once at instrument startup with
DIT=60sec and 
once at the end of the day-time calibrations with DIT=25sec.
