ssao Examples

Example 1. Search with results to standard output

Find the 10 brightest Bright Star Catalog Stars in 4-degree square box centered on 10:00:00 +30:00:00 J2000 and sort them by magnitude.
sbsc -hn 10 -r -7200 10:00:00 +30:00:00 J2000
produces the following: 
sbsc WCSTools 3.8.1, 3 June 2010, Doug Mink SAO

Example 2. Search with results to a file

Find all Bright Star Catalog stars within 2 degrees of M51 and write the results, sorted by right ascension, to a file
sbsc -thws r -r -7200 -o m51 13:27:48.311 +47:27:28.98 B1950
produces the following in the file m51.bsc:

Example 3. Find closest star

Find the closest SAO Catalog Star to 10:00:00 +10:00:00 B1950.
sbsc -a 10:00:00 +10:00:00 B1950
produces the following:
