This plot
Trending report for the so-called Reset Anomoly.
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.
Fig. 3. chip1: Same as Fig. 1, but showing the detail for DET.DIT less than 45 sec.
Fig. 4. chip1: Same as Fig. 2, but showing the detail for DET.DIT less than 45 sec.
Fig. 7. chip1: Same as Fig. 5, but showing the detail for DET.DIT less than 45 sec.
Fig. 8. chip1: Same as Fig. 6, but showing the detail for DET.DIT less than 45 sec.

General information
Click on any of the plots to see a close-up version.
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
