b	allSkyNIRSource	VULCANiDR	Galactic latitude	float	8	Degrees		pos.galactic.lat
b	gaia_source	GAIADR3	Galactic latitude	float	8	degrees		pos.galactic.lat
b_m_opt	twomass_psc	TWOMASS	Blue magnitude of associated optical source.	real	4	mag		phot.flux
batchID	ObjectThin	PS1DR2	Internal database batch identifier.	bigint	8			meta.id
best_use_cntr	allwise_sc	WISE	Cntr identification value of the source extraction that was selected as a candidate Catalog source in the duplicate resolution process for the group of associated sources that included this extraction. For the AllWISE Source Catalog, best_use_cntr = cntr. For the AllWISE Reject Table, best_use_cntr may be the cntr value of a corresponding source in the AllWISE Source Catalog.	bigint	8
best_use_cntr	wise_allskysc	WISE	Cntr identification value of the source extraction that was selected as a candidate Catalog source in the duplicate resolution process for the group of associated sources that included this extraction. For the All-Sky Release Catalog, best_use_cntr = cntr. For the All-Sky Reject Table, best_use_cntr may be the cntr value of a corresponding source in the All-Sky Release Catalog.	bigint	8		-99999999
bestDetection	StackObjectAttributes, StackObjectThin	PS1DR2	Identifies if this row is the best detection.	tinyint	1		255
