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
