This plot

This plot shows two QC parameters measuring the illumination distribution within IFU FLATs. Both kind of IFU flats contribute:

  • IFU health check flats generated from one (VIS) or two (NIR/UVB) raw flats and
  • IFU master flats generated from five (VIS) or ten (UVB/NIR) raw flats, acquired to calibrate science data.
 
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
