This plot
Trending plot for SKY_RMS, the RMS over all 16 mean sky values.
QC parameters is derived from photometric standard star calibrations.
Name:
Fits header: QC.MEAN_SKY,
QC1 DB: qc_mean_sky
Description:
The mean sky of the daily photometric standard star observations is taken; per detector.
The RMS from the sample of 16 detectors is taken as a measure for background variations over the VISTA FOV.
Setup:
INS.FILT1.NAME = Ks, J, H, Y, Z, and NB118
Find more information on the VIRCAM STANDARD STAR tutorial page.
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
