This plot

Trending plot for image quality.

QC parameters is derived from each detector of daily photometric standard star calibrations.

Name:
Fits header: QC ELLIPTICITY,
QC1 DB: qc_ellipticity

Description:
median ellipticity of the sources = (1-b/a).

Setup:
INS.FILT1.NAME = NB118

These plots describe:
Fig. 1. Average view: The QC parameter averaged over all detectors. This view is sensitive to common changes.
Fig. 2. Resolved View: The QC parameter resolved for all detectors.
Fig. 3. Scatter View: The standard deviation of the QC parameter, obtained from the sample of all detectors. This view is sensitive changes of individual detectors.
Fig. 4. Scoring View: Scoring values of all 16 QC parameters. Green = within the acceptance thresholds. Red = beyond the acceptance thresholds.

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
