RESOLVE_STATUS

Resolve status for an SDSS catalog entry. Only one of bits RUN_PRIMARY, RUN_RAMP, RUN_OVERLAPONLY, RUN_IGNORE, and RUN_DUPLICATE can be set. RUN_EDGE can be set for any object. To get a unique set of objects across the whole survey, search for objects with SURVEY_PRIMARY set. To get a unique set of objects within a run, search for objects with RUN_PRIMARY set.

Bit name	Binary digit	Description
RUN_PRIMARY	0	primary within the objects own run (but not necessarily for the survey as a whole)
RUN_RAMP	1	in what would be the overlap area of a field, but with no neighboring field
RUN_OVERLAPONLY	2	only appears in the overlap between two fields
RUN_IGNORE	3	bright or parent object that should be ignored
RUN_EDGE	4	near lowest or highest column
RUN_DUPLICATE	5	duplicate measurement of same pixels in two different fields
SURVEY_PRIMARY	8	Primary observation within the full survey, where it appears in the primary observation of this part of the sky
SURVEY_BEST	9	Best observation within the full survey, but it does not appear in the primary observation of this part of the sky
SURVEY_SECONDARY	10	Repeat (independent) observation of an object that has a different primary or best observation
SURVEY_BADFIELD	11	In field with score=0
SURVEY_EDGE	12	Not kept as secondary because it is RUN_RAMP or RUN_EDGE object
