Trending report for source peak value.
QC parameter is derived from photometric standard star calibration frames.
Name:
Fits header: QC.ZPOINT.PEAK,
QC1 DB: qc_zpoint_peak
Description:
The peak value of the photometric standard star PSF.
Values > 25000 ADU indicate saturation which results in rejection of the
QC.ATX0 value.
Setup:
INS.FILT1.NAME=Ks
These plots describe:
Fig. 1. chip4: The QC parameter for chip #4.
Fig. 2. chip3: The QC parameter for chip #3.
Fig. 3. Average: The QC parameter averaged over all detectors.
This view is sensitive to common changes.
Fig. 4. chip1: The QC parameter for chip #1.
Fig. 5. chip2: The QC parameter for chip #2.
Fig. 6. Scatter View: The standard deviation of the QC parameter, obtained from the sample of all detectors.
This view is sensitive changes of individual detectors.

Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
- 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
