Trending plot for Non-linearity at 10000 ADU in per cent.
QC parameters is derived from each detector monthly linearity frames.
Name:
Fits header: QC.LINEARITY,
QC1 DB: qc_linearity
Description:
From the stack of flat frames with different values of DIT of a constant luminosity source.
the observed relation between counts and DIT is compared against a linear
relation: counts = A + B * DIT. The QC.LINEARITY is the deviation at 10000 ADU
flux level in percent
Setup:
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.

General information
Click on any of the plots to see a close-up version.
If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
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
