In order to assist the Paranal astronomers with the assessment
of data quality, sets of reference frames are collected here, mostly taken
in standard configurations. They are sorted by instrument mode.
The reference frames are available as screen shots, to serve
as quick-look comparison with fresh data. In many cases, there are also headers,
fits files, and additional detail information. For some cases, there are also
reference pipeline products.
The Paranal astronomers can use these data to verify the quality
of the daily collected calibrations (for instance to see if the correct filter
has been used, if the flux level and profile is correct, if a feature
is normal or abnormal, etc.).
The set of reference frames will be updated whenever necessary
(for instance when a new grism or a new standard setting is commissioned, after
a technical intervention, etc.).
This web site is a joint effort of Paranal Science Operations
and the Quality Control Group (QC Garching). It is maintained by QC
Garching. We are happy to receive
suggestions about additions etc.
Information about pipeline processing can be found under QC
