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
