Name¶
susa2 - Find USNO-SA2.0 Catalog stars in a square on the sky
Synopsis¶
susac [options] [-b or -j] ra dec
Description¶
suac finds all of the U.S. Naval Observatory SA2.0 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 <RA> <Dec>
Output B1950 (FK4) coordinates around this center -d Sort by distance
from center instead of flux -h Print heading, else do not -j
<RA> <Dec> Output J2000 (FK5) coordinates around this center
-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 -r <radius> Search radius in
arcsec (default 10) -s Sort by right ascension instead of flux
-t Tab table to standard output as well as file -u <num>
Plate number for catalog sources (0=all) -v Verbose listing of
processing intermediate results -w Write tab table output file
