These are the trending plots for the SINFONI QC parameters derived from DARK frames.

These plots describe:

1. the median DARK level, as computed from each master dark frame.

2. the standard deviation of the median DARK level.

3. the root-mean-squared noise, as derived by subtracting two consecutive raw dark frames, computing a median standard deviation in
selected sub-windows, computing a median standard deviation in selected sub-windows in the difference image, and then normalizing to DET.DIT=1 second.

4. the fixed pattern noise, as computed by fitting a Gaussian to the histogram of the master dark frames. The fpn is simply the standard deviation of Gaussian.

5. the number of pixels with a high dark current.

6/7/8. the odd-even column stripes in the area of slitlet #25. If med(odd) = median of all odd columns in the area of slitlet #25
and med(even) = median of all even columns in the area of slitlet #25 then, this plot is defined as:
oes25 = 2 * (med(odd) - med(even)) / (med(odd) + med(even))
the plots show the effect for the first 3 raw files of the DARK

DARK current and RON higher than usual could be due to an increase of the detector temperature (INS.TEMP6.VAL), grating temperature (INS.TEMP13.VAL) or of the rack temperature (INS.TEMP6.VAL). Check also INS.SENS13.ST (Detector warm mode).
