This plot

Trending plots for standard zeropoints: B_JOHN .

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

DB Name: omegacam_std
Fits header: QC.ZEROPOINT_ELECTRON / QC.ZEROPOINT_ELECTRON.ERR
QC1 DB: qc_zeropoint_electron / qc_zeropoint_electron_err

Description:
The zeropoints are measured using flux units in electrons and are contained in the pipeline product frame ZEROPOINTS

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

These Health Check plots describe:
Fig. 1 Zpt_rSDSS_AVG: The B_JOHN zeropoints averaged over all 32 detectors. This plot is sensitive to any changes common to all detectors. Also, Paranal opslog data are included. The data from Paranal is filtered (s.t. mag.>=20.0) and averaged over the 8 detectors for which it is measured.
Fig. 2 Zpt_rSDSS_RMS: The rms of the B_JOHN zeropoints averaged over all 32 detectors.
Fig. 3 Zpt_rSDSS_ALL: The B_JOHN zeropoints for each individual detector. This plot is sensitive changes in individual 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
