sua2 - Find USNO-A2.0 Catalog stars in a square on the sky
sua2 [options] ra dec system
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

imcat - List catalog stars in FITS and IRAF image files
imcat [options] FITS or IRAF file(s)
Search given catalog withing area described by the world coordinate system in an image header. May be called as imuac to search the USNO A
1.0 catalog, imusac to search the USNO SA 1.0 catalog, or imgsc to search the HST Guide Star Catalog.
Options-b [<RA> <Dec>]
Output in B1950, optional new image center in B1950 (FK4) RA and Dec to replace that in image header
Reference catalog (gsc(=HST GSC), ua2(=USNO-A2.0), TMC(=2MASS Point Source Catalog), gsc2(=GSC II), ub1(=USNO-B1.0), local file,
-d Output RA,Dec positions in fractional degrees
-e Output in ecliptic longitude and latitude
-g Output in galactic longitude and latitude
-h Print heading, else do not
-i Print name instead of number in region file
-j [<RA> <Dec>]
Output in J2000, optional new image center in J2000 (FK5) RA and Dec to replace that in image header
Add this keyword to output from tab table search
-m [<bright magnitude>] <faint magnitude>
Limiting catalog magnitude(s) (default none, bright -2 if only faint is given)
Number of brightest stars to print
Set HST Guide Star object class to print (0=stars, 3=nonstars, -1=all, -2=band)
Initial plate scale in arcsec per pixel (default from file)
Write SAOimage region file with this shape, o=circle, s=square, d=diamond, +=cross, and x=X, with the radius scaled with magnitude
unless specified with a -r command line entry. v will cause stellar Guide Stars to plot with a + and nonstellar Guide Stars to plot
with an x. If character is is preceded by p, the size specified by the -r command is assumed to be in pixels, not arcseconds. A p
alone specifies a circle in pixels.
Write SAOimage region file with shapes (default CIRCLE) of this radius in arcseconds. SAOimage can then read this file, with will
have positions and radii in pixels and plot it over an image. If the radius is specified as zero, the output radii will scale
between 5 and dim/100 over the range of magnitudes of sources found in the image area. If the -q option is specified with a 'p' in
it, this number is assumed to be in pixels instead of arcseconds.
Sort by (d)eclination, (m)agnitude, (n)o sort, (p)distance from center, (r)ight ascension, image (x) or (y).
-t Tab table to standard output as well as file
-u num USNO catalog single plate number to accept
-v Verbose listing of processing intermediate results
-w Write tab table output file imagename.cat
-x x y X and Y coordinates of reference pixel (default is CRPIXn or center of image)
Epoch of image for proper motions
-z Use AIPS classic projections instead of WCSLIB; use CD matrix or CDELT instead of polynomial solution.
