Number of hot and cold pixels, as calculated by the "naco_img_dark"
recipe of the NACO pipeline, shown for three daily acquired
read modes.
Default pipeline recipe parameters are used:
hot pixel are pixel with a dark current above median + 10 ADU.
cold pixel are pixel with a dark current below median - 6 ADU.
Since 2015 we use: --hot_t = 14 ADU and --cold_t = 10 ADU.
For the daily darks with
setup FNS_HS_300, the large scale background pattern has a higher amplitude
than the amplitude of the hot and cold pixels. Therefore values of this setup is not
scored.

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
