This plot

Values are generated for both CHIP1 and CHIP2, 2x2 binning only. Photometric nights are selected from the Absorption Monitor. Zeropoints are 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!  


General information

Click on any of the plots to see a close-up version.

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
  • outliers are marked by a red asterisk. They are defined as data points outside the threshold lines
  • "aliens" (= data points outside the plot Y limits) are marked by a red arrow ( or )
  • you can download the data for each parameter set if the 'Data downloads' link shows up
