This plot

Trending plot for CirrusTest Parameter obtained from detector 10. (since 2018-10-01: for EXTNAME=AVG)

QC parameters is derived from the twilight flat raw flux sequence of detetcor #10. (Since 2018-10-01: for the average over 16 detectors)

Name:
Fits header: (not available),
QC1 DB: qc_twilight_expfitrms
Description:
Under photometric and clear conditions the sky brightness is (de)inreases during (dusk)dawn in a continuous manner. Thin or thick cirrus moving through the FOV disturb the continuous flux trend. The function flux(time)= A + B * exp ( - C * (D - time)) is fit to the raw flux sequence and the RMS of the fit is considered as a measure of the sky brightness continuity within the FOV. The CirrusTest parameter is the RMS of the exponential fit to fluxes retrieved from the twilight flat raw frames. It is a quality parameter of the master twilight flat. Twilight flat flux sequences with significant deviantions from flux(time) will be discarded.

Setup:
INS.FILT1.NAME = Ks, J, H, Y, Z, NB118

General information

Click on any of the plots to see a close-up version.

The latest date is indicated on top of the plot.

If configured,

  • data points belonging to the latest date are specially marked
  • 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
