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.
essential notes:
  • According to the GCVS team, YY Dra is considered to be another star. Whereas DO Dra is a well-documented dwarf nova, YY Dra is a lost eclipsing binary, which original coordinates are probably erroneous (see discussion in 1987IBVS.3079....1P and 1988IBVS.3154....1K)


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