Trending plots for standard zeropoints: u_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 = u_SDSS/1/1/normal/normal
These Health Check plots describe:
Fig. 1
Zpt_rSDSS_AVG: The u_SDSS 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 u_SDSS zeropoints
averaged over all 32 detectors.
Fig. 3
Zpt_rSDSS_ALL: The u_SDSS zeropoints for each individual
detector. This plot is sensitive changes in individual detectors.

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
