Trending plots for standard zeropoints: r_SDSS .
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 = r_SDSS/1/1/normal/normal
These Health Check plots describe:
Fig. 1
Zpt_rSDSS_AVG: The r_SDSS zeropoints averaged over all 32
detectors. This plot is sensitive to any changes common to all
detectors.
Fig. 2 Zpt_rSDSS_RMS: The rms of the r_SDSS zeropoints
averaged over all 32 detectors.
Fig. 3 Zpt_rSDSS_ALL: The r_SDSS
zeropoints for each individual detector. This plot is sensitive
changes in individual 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.

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
