2012-05-22: The QC cluster (compute platform for QC services) is currently not available. The HC monitors for OMEGACAM, VIRCAM and HAWKI will be frozen until about 2012-05-25.
The zeropoint is calculated on the star of the month. It is calculated using
zpoint=mag + 2.5*log10(flux/DIT)
where mag is the magnitude of the object in N band
flux is the Target Photometry of beam A or B (measured in bin2)
DIT is the detector DIT
There are no correction applied
