This plot
This is the trending plot of the daily check flat
taken as part of the daily health check procedure.
This plot describes the median of checkflat product frames :
The product is simply : raw checkflat divided by the reference checkflat
1. The flux in UL window from 206,718 to 306,818, size=100x100, centered in UL quadrant at 256,768
2. The flux in CC window from 462,462 to 562,562, size=100x100, centered in 512,512
3. The flux in UR window from 718,718 to 818,818, size=100x100, centered in UR quadarant at 768,768
4. The flux in LL window from 206,206 to 306,306, size=100x100, centered in LL quadrant at 256,256
6. The flux in LR window from 718,206 to 818,306, size=100x100, centered in LR quadrant at 768,768

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
