Quality information in VO Catalogs

DENIS Catalogue

We use the quality information in the Iflg, Jflg, Kflg flags (one for each band) provided by the DENIS catalogue in Vizier.

where the possible values are described as:

We consider flag=0000 as good quality. Bad otherwise. That is:

  • Iflg!=0000 → DENIS/DENIS.I: bad
  • Jflg!=0000 → DENIS/DENIS.J: bad
  • Kflg!=0000 → DENIS/DENIS.Ks: bad

See the catalogue description in Vizier (you can also see a local copy here if the link does not work).
