This plot

This is the trending plot for the ISAAC QC parameters derived from science imaging pipeline products. The image quality is measured:
Sources are detected from the final imaging product:,br> qc_fwhm_ac = median FWHM of all sources in arcsec
qc_fwhm_pix = median FWHM of all sources in pixel units
qc_mode = maximum of the FWHM histogram (most frequent FWHM)
qc_iq = specially cleaned mean of FWHM of all sources in arcsec

These plots describe qc_iq:

Fig. 3.image quality, for LW Ks.
Fig. 4.image quality, for LW L.

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
