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:

  • tet01 ORI B East = COUP 778 and tet01 ORI B West = COUP 766. 2005ApJS..160..557S
  • Spatially resolved into 4 stars B1 to B4; B1 is the actual SB*, sometimes described as B1+B5 in the literature (e.g.2003ApJ...599..537C). Component B5 is not in Simbad (not spatially resolved).
