Trending plot for Average of raw frame medians.
QC parameters is derived from the raw frame input stack.
Name:QC_RAWMED_AVG
Fits header: not available,
QC1 DB: qc_twflat_raw_avg
Description:
Retrieve from each raw frame the median of the flux level. Take the avergae of all raw frame medians.
Setup:
INS.FILT1.NAME = Z
These plots describe:
Fig. 1. Average view: The QC parameter averaged over all detectors.
This view is sensitive to common changes.
Fig. 2. Resolved View: The QC parameter resolved for all detectors.
Fig. 3. Scatter View: The standard deviation of the QC parameter, obtained from the sample of all detectors.
This view is sensitive changes of individual detectors.
Fig. 4. Scoring View: Scoring values of all 16 QC parameters.
Green = within the acceptance thresholds.
Red = beyond the acceptance thresholds.

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 ↓)
