This plot
This plot shows the stdev of the master darks's median row resolved per detector quadrant
for the daily acquired DARKs in DoubleReadResetRead, HighSensitivity, DIT=0.5sec mode.
The plot was introduced to monitor the enhanced noise in every 8th column in the
upper right (UR) detector quadrant, which started on 2012-02-10 and terminated
at 2012-03-30.
The rms of the median row is dominated
by 'vertically aligned' structures, like the 8-col noise.
In the absence of the 8-col noise the residual RMS is due to the fixed
pattern noise in the master dark.
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
