This plot

The FlatBlue+1 and FlatBlue+2 lamps are used for imaging screen flats.
The RMS is calculated from the master screen flat image pixel sample (2x2 binning) X: @200 @1800 and Y: @400 @800 covering the unvignetted area of chip1 and chip2.

DB Name: fors2_scrflat
TPL.ID: FORS2_img_cal_scrflat
QC1 DB parameter: sigma_master

 
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
