B.2.2 Examples

Here are some examples of cdsskymatch:

stilts cdsskymatch cdstable=II/246/out find=all
                   in=dr5qso.fits ra=RA dec=DEC radius=1 out=qso_2mass.fits
Matches a local catalogue dr5qso.fits against the VizieR table II/246/out (the 2MASS Point Source Catalogue). The search radius is 1 arcsecond, and all 2MASS sources within the radius of each input source are returned.
stilts cdsskymatch cdstable=simbad find=best
                   in=sources.txt ifmt=ascii ra=RAJ2000 dec=DEJ2000 radius=8.5
                   blocksize=1000 icmd=progress omode=topcat
This finds the closest object in the SIMBAD database within 8.5 arcsec for each row of an input ASCII table. Uploads are done in blocks of 1,000 rows at a time, and progress is displayed on the console. When the match is complete, the result is sent directly to a running instance of TOPCAT.
