General news: NOTE: The Health Check and calChecker services are moved to qcFlow on an instrument by instrument basis. The current pages will not be updated any longer once the move has been finished.
SPHERE news: Note that the current Health Check monitor runs with an incomplete pipeline and an incomplete set of QC1 parameters. QCG can currently not guarantee completeness and significance at the usual level.
Report news: 2022-04-16 Red flat on ron is of unknown origin. QC1 database and products don't show any value out of range.

This plot

The QC parameter qc_ron is not calculated by the pipeline but by a QC script. From the raw frame fits cube, five planes are extracted (plane 6 to 10), and for each pixel the stdev (out of five independent reads) is calculated. The median over all pixels stdev is taken.

The parameter qc_ron contains statistical noise, which is composed of a static detector readout noise component of 2.47 ADU and a exposure time dependent component of

sqrt(counts / gain)

corresponding to the shot noise induced by the background radiation. In box (4) the function 2.47 + sqrt(-6 + 10.2 * DIT / 3.6) is overplotted.

The three reference setups (DIT=2, 8, and 30) are scored according to the dashed lines in boxes 1,2, and 3. All other setups are scored according to the non-linear arithmetic relation indicated by the dashed curves in box 4.

  • upper threshold = sqrt((-6 + 10.2 * DIT)/3.6)+2.47 -2.0-0.1*DIT
  • lower threshold = sqrt((-6 + 10.2 * DIT)/3.6)+2.47 +3.0+0.1*DIT

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
