Quality information in VO Catalogs
MSX6C Infrared Point Source Catalog
We use the quality information in the q_B1, q_B2, q_A, q_C, q_D, q_E flags (one for each band) provided by the MSX catalogue in Vizier.
where the possible values are described as:
We consider flag >=2 as good quality. Bad otherwise. That is:
- q_B1 <=1 → MSX/MSX.B1: bad
- q_B2 <=1 → MSX/MSX.B2: bad
- q_A <=1 → MSX/MSX.A: bad
- q_C <=1 → MSX/MSX.C: bad
- q_D <=1 → MSX/MSX.D: bad
- q_E <=1 → MSX/MSX.E: bad
