This plot

This is the Health Check plot for checking saturation of GIRAFFE flat field calibration data. A saturated flat field can still be used for localization of the fibre signal (unless in extreme cases), but the information related to pixel-to-pixel gain variations, to fringing and to fibre-to-fibre sensitivity is lost in the saturated regions. Therefore all measured flats are monitored in terms of saturated pixels.

We display the QC1 parameter qc_numsat (QC.NUMSAT) which registers the number of pixels close or at saturation (> 60,000 ADU). The alert level is set to 1000 ADU which is more or less arbitrary but experience shows that data with higher values indeed have an issue.

This plot monitors all flat field data. The HC flats (L543.1) are displayed in colour.

The values are usually 0, a flat with saturation stands out clearly. The upper threshold is more or less arbitrary, it is used to get an alert.  


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
