Description

12       suac  finds all of the U.S. Naval Observatory A2.0 Catalog objects in a
13       specified region of the sky and lists their sky  positions  and  magni‐
14       tudes  in order of brightness. Output is to standard out, unless the -w
15       flag is set, in which case it goes to objectname.uac or search.uac.  It
16       is a link to scat.

Options

19       -a list single closest catalog source -b Output B1950 (FK4) coordinates
20       -d Sort by distance from center instead  of  flux  -e  Output  ecliptic
21       coordinates -f Output search center for other programs -g Output galac‐
22       tic coordinates -h Print heading, else do not -i Print  catalog  object
23       name,  not  catalog  number  (=ua2_region_number) -j Output J2000 (FK5)
24       coordinates -l Print center and closest star on one  line  -m  [<bright
25       magnitude>]  <faint  magnitude>  Limiting catalog magnitude(s) (default
26       none, bright -2 if only faint is given) -n <num>  Number  of  brightest
27       stars  to  print -o <name> Object name used to name output file -p Sort
28       by distance from search center instead of brightness -q <years> Equinox
29       of  output positions in years -r <radius> Search box half-width in arc‐
30       sec or dd:mm:ss If negative, this is a radius; if two numbers, first is
31       in right ascension, second is in declination. (default is 10, that is a
32       20x20 arcsec box) -s Sort by right ascension instead of flux -t Tab ta‐
33       ble  output  -u  <num>  Print X Y instead of number in front of non-tab
34       entry -v Verbose listing of processing intermediate  results  -w  Write
35       tab  table  output  file  imagename.uac -y Epoch of output positions in
36       years
