Other object types:
Sy1 (), Rad (Ref,ICRF,...), QSO (Ref,2015Ap&SS.357...75M,...), gam (3EG,EGR,...), Bla (Ref,2016ApJS..224...26M,...), X (Ref,RX,...), AGN (Ref,CGRaBS), IR (2MASS,WISE), * (Gaia)

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!).
