This plot

The recipe midi_profile is applied to chopped PHOTOMETRY frames. For each window on the detector (Data1, Data2 for HIGH_SENS) and Data1 to Data4 for SCI_PHOT, a profile is identified and a mask is created. The recipe also calculates the y position of the mask in 5 different bins
These results are used to monitor the vertical position of the spectrum (using the bin 3: HIERARCH ESO QC Y1 CENT BINNED3). A problem has been detected with the PRISM (the y position is moving 1 pixel per year).
 

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
