The Reset Anomoly is a feature of certain detectors whereby after the detector reset there is a period of time during which the rate of dark current accumulation varies before settling into a (more or less) constant rate of accumulation, e.g. as see in ISAAC.
HAWK-I apparently does NOT suffer from a Reset Anomoly as seen in this report.
Each plot displays the median of the DARK as a function of DIT
Name:
Fits header: DET.DIT and QC.RAW.MEDIAN.MEAN
QC1 DB: det_dit and qc_dark_med in hawki_dark.
Description:
The mean of the raw dark medians is plotted as a function of Detector
Integration Time (DIT).
Setup:
All DITs
These plots describe:
Fig. 1. chip4: The QC parameter QC.RAW.MEDIAN.MEAN as a funtion of DET.DIT for chip #4.
Fig. 2. chip4: The QC parameter QC.RAW.MEDIAN.MEAN as a funtion of DET.DIT for chip #3.
Fig. 5. chip4: The QC parameter QC.RAW.MEDIAN.MEAN as a funtion of DET.DIT for chip #1.
Fig. 6. chip4: The QC parameter QC.RAW.MEDIAN.MEAN as a funtion of DET.DIT for chip #2.
