This plot
Trending is done only for the SR collimator. For the old CCD (until
2007-03-25) only 1x1 binning data are trended. For the new CCDs (since
2007-04-01) only 2x2 binning data are trended. Photometric nights are
selected from the Absorption Monitor. Zeropoints are per frame 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!

If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
statistical averages are indicated by a solid line, and thresholds by broken lines
