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.

This plot

This plot shows the IRDIS DBI background in ADU/sec.

  • (1) negligible background in the H-band (no ND filter)
  • (2) stable background for the K-band
  • (3) no background for H-band plus neutral density filters
  • (4) K-band background correlates with the temperature of the neutral density filters. Both temperature values (red and green little dots) are given in [C] and have been scaled via:
    T(in the plot) = 1.452 T - 1.409
    to fit the background rate values given in [ADU/sec].
Note for (4): The neutral density filters (here ND_1.0 and ND_2.0) used for IRDIS are located in the CPI. The same background is measured for both ND filters, hence it is independent on the ND filter throughput. The background is correlated with the CPI temperature.  
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
