This is the trending plot for the ISAAC Aladdin QC parameters derived from DARK frames for read mode DoubleCorrLowBias
and two DIT DIT=2sec and DIT=5sec

These plots describe:
1. RON12 for DIT=2sec,
2. RON23 for DIT=2sec,
3. Dark current for DIT=2sec,
4. RMS for DIT=5sec
5. as Fig.1 but for DIT=5sec
6. as Fig.2 but for DIT=5sec
7. as Fig.3 but for DIT=5sec
8. as Fig.4 but for DIT=5sec

RON is derived twice, once from the the first pair of raw frames (RON12 = black points), and once from the second pair of raw frames (RON23 = green points). DoubleCorr detector read modes (= ResetReadRead) show no significant difference between RON12 and RON23.
The dark is the median of the MASTER_DARK product.
The RMS is the standard deviation derived from the three raw frame median values and is a measure of the short-term dark stability fir the given DIT.

Other QC parameters related to detector properties (like structural noise, linearity) are trended.
