This plot
This is the trending plot of the daily check flat
taken as part of the daily health check procedure.
This plot describes standard the flux ratio derived from RAW checkflat frames.
The flux ratio UL/CC is the flux in the UL window normalized to the flux in the CC window:
1. The standard deviation in UL window from 50,874 to 150,974, size=100x100, 50 pixels away from the edge of the raw checkflat frame
3. The standard deviation in UR window from 874,874 to 974,974, size=100x100, 50 pixels away from the edge of the raw checkflat frame
4. The standard deviation in LL window from 50,50 to 150,150, size=100x100, 50 pixels away from the edge of the raw checkflat frame
6. The standard deviation in LR window from 874,50 to 974,150, size=100x100, 50 pixels away from the edge of the raw checkflat frame

General information
Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
- 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
