This plot
Trending report for effective linearity.
The plot shows the difference at 10 000 ADU between the flux
obtained from 2nd order polynomial fit of flux vs. exposure time and
the flux predicted by the linear term only, normalized by the polynomial flux.
More information can be found on
the plot tutorial page
QC parameter is derived for each detector from the data of the monthly acquired detector
monitor template.
Name:
Fits header: QC.LIN.EFF,
QC1 DB: qc_lin_eff
Description:
Linearity correction factor at 10 000 ADU.
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.

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
