  • 2009-05-28: Scoring (red/green squares in the group bar and in the navigation bar) is on the detector average (Fig. 1) and detector rms (Fig. 3) values alone.
  • 2009-05-28: Scores of individual detector values (Fig. 4) are for detailed analysis but do not contribute to the overall instrument score.

This plot

Trending plot for image quality.

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

Name:
Fits header: QC.IMAGE_SIZE,
QC1 DB: qc_image_size

Description:
The median of the sample of sources FWHM.

Setup:
INS.FILT1.NAME = Z

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
