This plot
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 rootmeansquared noise, as derived by subtracting two consecutive raw dark frames, computing a median standard deviation in
selected subwindows, computing a median standard deviation in selected subwindows 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 oddeven 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

here.
Other QC parameters related to detector properties (like dark level,
linearity, gain, etc.) are also trended
here.
General information
Click on any of the plots to see a closeup 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
