Name

       sua2 - Find USNO-A2.0 Catalog stars in a square on the sky

Synopsis

       sua2 [options] ra dec system

Description

       suac  finds  all  of the U.S. Naval Observatory A2.0 Catalog objects in a specified region of the sky and
       lists their sky positions and magnitudes in order of brightness. Output is to standard out, unless the -w
       flag is set, in which case it goes to objectname.uac or search.uac. It is a link to scat.

Options

       -a list single closest catalog source -b Output B1950 (FK4) coordinates -d Sort by distance  from  center
       instead  of  flux  -e  Output  ecliptic  coordinates -f Output search center for other programs -g Output
       galactic coordinates -h Print heading, else do not -i Print  catalog  object  name,  not  catalog  number
       (=ua2_region_number)  -j  Output  J2000 (FK5) coordinates -l Print center and closest star on one line -m
       [<bright magnitude>] <faint magnitude> Limiting catalog magnitude(s) (default none,  bright  -2  if  only
       faint  is  given)  -n  <num> Number of brightest stars to print -o <name> Object name used to name output
       file -p Sort by distance from search center instead of brightness -q <years> Equinox of output  positions
       in  years  -r  <radius> Search box half-width in arcsec or dd:mm:ss If negative, this is a radius; if two
       numbers, first is in right ascension, second is in declination. (default is 10, that is  a  20x20  arcsec
       box)  -s Sort by right ascension instead of flux -t Tab table output -u <num> Print X Y instead of number
       in front of non-tab entry -v Verbose listing of processing intermediate results -w Write tab table output
       file imagename.uac -y Epoch of output positions in years
