This plot

This is the trending plot for the ISAAC QC parameters derived from science imaging pipeline products. The sky brightness is measured:
Dark subtracted and flatfielded raw science imaging frames are used for the sky extraction subroutine, that determines the sky level in ADU for each raw frame. The median sky level of the stack is taken. The counts are converted in instrumental magnitudes per square arc second. No extinction correction is applied, no photometric zeropoint is applied.

These plots describe:
Fig. 1.sky brightness, for SW SZ.
Fig. 2.sky brightness, for SW J.
Fig. 3.sky brightness, for SW Js.
Fig. 4.sky brightness, for SW H.
Fig. 5.sky brightness, for SW Ks.

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
