This plot
This plot shows the IRDIS readout noise (RON) values extracted from from dark exposures of the three regularly acquired
setups
- DIT=2, NDIT=40
- DIT=8, NDIT=25
- DIT=30, NDIT=15
RON values are extracted by a QC script in the same manner as for IFS darks.
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
