Trending & QC1 Pipelines Data packages
(until P87)

At ESO Headquarters in Garching, calibration data from all Paranal instruments (VLT, VLTI, survey cameras) are processed, their quality is checked and monitored. This is the task of the Quality Control and Data Processing Group ("QC Garching"). This process is part of the back-end of the Data Flow System.

QC Garching has the following main tasks:

  • monitor the calibration plan and report issues back to Paranal Observatory
  • create master calibration data, control their quality and certify them
  • perform instrument trend analysis and feed back the results to Paranal Observatory
  • deliver master calibration data to the archive
  • process pre-imaging data


  • Since October 2011, QC Garching does not process anymore science data.
  • The creation of PI packages has also been terminated. As before, PIs can access their data on the ESO User Portal.
