Archiving of the Data
The data produced at ESO telescopes during each observing night, as well as their daytime calibrations, are stored in the ESO Archive. With the ESO Archive Query Form, users can obtain information on the observations done with ESO telescopes and their instruments.
The Principal Investigators of successful proposals for time on ESO telescopes, and their data delegates, have exclusive access to their scientific data for the duration of a proprietary period, normally of one year. The ESO Data Access and Publication Policy provides more information. Calibration data are not subjected to any proprietary period and they can be requested as soon as they are available in the Archive.
All calibration data from the VLT are processed and quality-checked by the Quality Control and Data Processing Group.
