This plot

Trending plots monitoring the flux in flat-fields taken with the Halogen lamp or with the IR emitter.

These flats are measured daily with a reference wavelength of 2199.1 nm. The exposures are taken for QC purposes; only the Halogen lamp is also used in other flat-field measurements that are intended for science calibration.  

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
