This plot

These are the trending plots for the SINFONI QC parameters derived from the PSF calibration frames. PSF standard star monitoring has been implemented beginning 2009-05-01.

The intent is to monitor the MINIMUM flux of the PSF star to insure that it has an adequate S/N. Flux levels should be above 3 ADU/pixel within a 3 sigma aperture for the K and H+K-band. In the case of the J and H-band PSF stars, the minimum allowed flux level is 2 ADU/pixel within a 3 sigma aperture.

The PSF standard star is often used to test the centering of science exposures. Therefore, we monitor the radial offset from the nominal field center: R = sqrt[ (x-x0)^2 + (y-y0)^2 ].

Find more information about SINFONI PSF calibration data here.

Other QC parameters are also trended here.  


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
