Keywords

WAS catalogues and indexes thousands of keywords for every processed target that is ingested. Most of these keywords originate from the processing pipelines or the observation catalogues provided by users, but others are specifically provided by the WAS.

RELEASE

This is a two-digit number in the format x.y, for example 2.1. This first digit matches or will match the corresponding public Data Release (DR).

NIGHT-OPS

The night when the observation was taken.

INGESTION_DATE

WAS ingestion date.

WNAME

Name internal to the WAS, with which every target is uniquely identified and indexed. WNAME corresponds to the CNAME in the case of single fibres (IFU, MOS), or to the union of CCNAME+PATCH in the case of data cubes (IFU).

L1_FILENAME

Name of file containing L1 data products of the CPS pipeline, provided by CASU. Format is arm1.fits,arm2.fits

L2_FILENAME

Name of file containing L2 data products of the APS pipeline, provided by CASU.

EMBARGO

Indicates the proprietary period of the data, if any. This keyword is associated with Open-Time programs.

COORDS

Contains the sexagesimal coordenates of the field in the case of MOS targets and IFU single fibres, and the central spaxel in the case of IFU targets.

TARGCOORDS

Contains the sexagesimal coordinates of the fibre in the case of MOS and IFU single fibres, and the coordinates of the central spaxel in the case of IFU targets.

Renamed keywords

There are some keywords in the database that have been renamed to avoid overwriting when they come from different detectors but use the same name within the FITS files headers.
