This plot

Trending plots for standard star image quality (Ellipticity): r_SDSS .

QC parameters are derived from each of 32 detectors of OmegaCAM STD,ZEROPOINT frames.

DB Name: omegacam_std
Fits header: QC.STD.ELLIPTICITY
QC1 DB: qc_std_ellipticity

Description:
The ellipticity (1 - b/a) is measured only for source identified as stellar (CLASS_STAR >= 0.90 from the SExtractor detection) and is contained in the pipeline product frame ZEROPOINTS

Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED = 1/1/normal/normal

These Health Check plots describe:
Fig. 1 ellip_rSDSS_AVG: The r_SDSS stellar ellipticities (1-b/a) averaged over all 32 detectors. This plot is sensitive to any changes common to all detectors.
Fig. 2 ellip_rSDSS_ALL: The r_SDSS stellar ellipticities (1-b/a) for each individual detector. This plot is sensitive changes in individual detectors.
Fig. 3 ellip_rSDSS_RMS: The rms of the r_SDSS stellar ellipticities averaged over all 32 detectors.

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
