ALFOSC Zero point monitoring
Zero point monitoring from September 2000 to October 2001.
Observations were performed at three different airmasses.
UBVRI zero-point monitoring(for CCD#7)
ALFOSC CCD#8 UBVRi Zero Point monitoring
The zeropoints are measured when ever one of the selected photometric
standard star is observed using
the "standard" filters (U#7,B#74,V#75,R#76,i#12). The extinction values
have been taken from Carlsberg Meridian Telescope.
Note, that in the table below, there might be "bad" points
due to e.g. high extinction and the errors do not include the uncertainty
of the colour term.
The CCD-frames are overscan subtracted and the magnitudes are measured
using IRAF/APPHOT and finally the zero points are measured using
FITPARAMS non-interactively. The table below shows the results with
fixed extinction & colour term and using gain of 0.34 e-/ADU
(before 26.06.2011: 0.765 e-/ADU).
