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
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.

The latest date is indicated on top of the plot, data points belonging to that 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
"aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
