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 deviation of RAW checkflat frames:

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
2. The standard deviation in CC window from 462,462 to 562,562, size=100x100, center of the array 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
