This plot

Trending plots for the standard star image quality (FWHM) vs. the seeing as measured by the DIMM site-monitor.
z_SDSS filter.

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

DB Name: omegacam_std
Fits header: QC.AMBI.SEEING, QC.STD.SEEING
QC1 DB: qc_ambi_seeing, qc_std_seeing, qc_delta_fwhm

Description:
The FWHM (arcsec) is measured only for sources identified as stellar (CLASS_STAR >= 0.90 from the SExtractor detection)
and are contained in the pipeline product frame ZEROPOINTS.
The DIMM seeing has been adjusted to the wavelength and airmass of the standard star observation.

Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED / INS.FILT1.NAME = 1/1/normal/normal/z_SDSS

These Health Check plots describe:
Fig. 1 IQ_zSDSS: A one-to-one comparison of the image quality achieved by OmegaCAM and the seeing as measured by the DIMM. The plot shows the FWHM of the stars matched from the secondary standard catalogue and the corrected DIMM values at the moment of observation plotted against one another (in arcsec). The values for each of the 32 detectors is shown.
#The most recent data points are marked in magenta.

Fig. 2 Delta_IQ_zSDSS: shows Delta_IQ = OmegaCAM standard star FWHM - DIMM seeing for all 32 detectors.
This parameter is scored.

Fig. 3 score_outliers: Scores of the z_SDSS Delta_IQ_zSDSS values as measured for each of the 32 detectors.
Green = within the defined thresholds.
Red = beyond the defined 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
