Trending is done only for the SR collimator. Photometric nights are
selected from the Absorption Monitor. Zeropoints are per night for flux in
e-/sec, not in ADU.
Do not use these zeropoints for science
data. They are reduced assuming a standard extinction value, which
may not be correct for an individual night!
Large uncertainties are mostly due to nights with few stars.
