Quality information in VO Catalogs
UKIDSS Large Area Survey DR10
We use the quality information in the *ppErrBits flags provided by the UKIDSS/LAS catalogue in the WFCAM science archive.
We consider *ppErrBits < 256 as good quality for each band. Bad otherwise. That is, for instance:
- yppErrBits > 255 → UKIRT/UKIDSS.Y: bad
- hppErrBits > 255 → UKIRT/UKIDSS.H: bad
