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!).
Some important notes on this object about identifications and objects associations.
notes:

  • This binary system is designated as "GG Tau Aa" in 1999ApJ...520..811W, or as "GG Tau A+a" (i.e. bright component "A" + fainter component "a"). This is very confusing with the usual nomenclature in which the system is "Aa,Ab", the brightest component is "Aa", and the fainter one "Ab". In the literature, "GG Tau Aa" means sometimes the system, sometimes the component.
