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 magni-
       tudes 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
