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
