Abstract (from CDS):

In this paper we describe the construction of a Compiled Catalogue (CC) of about 30000 stars in a nearby region of star formation including the Per OB2 association. The CC is a photometric and astrometric survey with the center at (α,δ)J2000=(3h51m36s, 34°36') and radius of 10 degrees. The CC is based on recently published astronomical catalogues, e.g. Hipparcos and Tycho-2, and supplemented by relevant astrophysical data from numerous data sources. The CC is complete down to V=11.6mag, in general, and to V=18.5mag in the one square degree field centered around the IC 348 cluster. We describe the reduction procedures allowing us to put the data onto one homogeneous system, i.e., the coordinates and proper motions on the Hipparcos system and the photometry on the Johnson system. Typical accuracies of 1... 20 mas for coordinates, 1... 3mas/yr for proper motions and 0.01... 0.05mag for B, V magnitudes were achieved for the bright CC stars (V<12mag). For ≃7000 stars we also collected parallaxes and spectral classes. Down to the completeness limit of the CC, a preliminary proper motion selection yielded more than 1000 probable members of Per OB2. The catalogue is available in electronic form from the CDS at Strasbourg.

within 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!). sed-help-icon
