Basic data :
ICRF J061251.1+412237 -- BL Lac - type object
Origin of the objects types :

(Ref) Object type as listed in the reference "Ref"
(acronym) Object type linked to the acronym according to the original reference
() Anterior to 2007, before we can link the objet type to a reference, or given by the CDS team in some particular cases

Other object types:
Rad (ICRF,B3,...), gam (1FGL,2FGL,...), Bla (Ref,[MGL2009],...), BLL (Ref,[VV2010b]), AGN (Ref,CGRaBS), IR (2MASS,WISE), * (Gaia), QSO (Ref)
Syntax of coordinates is : "ra dec (wtype) [error ellipse] quality bibcode" :

within radius arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).

The link on the acronym of the identifiers give access to the information for this acronym in the dictionary of nomenclature.
