susa1 Examples

Example 1. Search with results to standard output

Find the 10 brightest USNO-SA1.0 stars in a 1-degree square box centered on 10:00:00 +30:00:00 J2000 and sort them by right ascension.

susa1 -s r -hn 10 -r -1900 10:00:00 +30:00:00 J2000

produces the following:

Example 2. Search with results to a file

Find all USNO-SA1.0 stars within 5 arcminutes of M51 and write results to a file

susa1 -twr 300 -o m51 13:27:48.311 +47:27:28.98 B1950

produces the following in the file m51.usa1:

Example 3. Find closest star

Find the closest USNO-SA1.0 star to 10:00:00 +30:00:00 J2000

susa1 -a 10:00:00 +30:00:00 J2000

produces the following:

susa1 -h 1350.00000001-1350.00000010x0.00000001

produces the following:
