This plot
This plot shows the optical CCD dark current values and RMS as derived from the
zimpol dark recipe for read mode StandardImaging. The recipe expresses dark values in units of the
used EXPTIME (here per 100 sec), the values in the plot are scaled to ADU/hour.

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 (↑ ↓ you can download the data for each parameter set if the 'Data downloads' link shows up
