This plot

Trending plots monitoring the stability of flat fields.

Daily monitoring of flats is executed for three settings with reference wavelengths 1090.4, 3218.6, and 4092.9 nm. Only data for chip 3 are plotted here because the structure of the flats is unstable especially for chips 1 and 4.

The first row shows the mean flux level of the flats. A sudden decrease of the level below the typical variations could indicate a problem (e.g. with the halogen lamp). The second row has the rms measured over the illuminated area. A change would indicate a change in the overall structure of the flat.

As of March 2010, Paranal values are not plotted for rms because they deviate strongly from QC Garching values (because of different recipe parameters).

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
