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
