ngc4725

Gaia DR2: For now, Gaia DR2 data are not in SIMBAD, it is available in Vizier. The CDS will perform a cross-identification of Gaia DR2 with the astronomical objects in the SIMBAD bibliographic database. This will be done with very strict criteria in order to avoid erroneous cross-identifications. Especially, only the 6.5 milllions objects with subarseconds coordinates will be searched in Gaia DR2. Expected to be ready on June 30, 2018.

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!).
