This plot

This plot shows the median counts of the brightest non-rejected flat used by the detector monitoring recipe.

upper threshold = 46000 ADU: Due to the inhomogenous illumination of the VIS imaging flats, the most illuminated pixel regions begin to saturate (counts = 65535 ADU) for frames with median counts > 46000 ADU.

lower threshold = 40000 ADU: Sampling smaller flux ranges means covering the linear part of the of the detector response curve only. The non-linearity expressed as a fraction at the reference flux level of 50000 ADU should be based on a flux range exceeding the 40 000 ADU. Otherwise the linearity QC parameter becomes more and more a function of the flux range.  


General information

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

The latest date is indicated on top of the plot.

If configured,

  • data points belonging to the latest date are specially marked
  • 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
