Example 1. Search with results to standard output

Find the 10 brightest Hipparcos Catalog Stars in a 1-degree square box centered on 10:00:00 +10:00:00 J2000 and sort them by magnitude.

ship -hn 10 -r -1800 10:00:00 +10:00:00 J2000

produces the following:

Example 2. Search with results to a file

Find all Hipparcos Catalog stars within one degree of M51 and write the results to a file

ship -wtsr -r 3600 -o m51 13:27:48.311 +47:27:28.98 B1950

produces the following in the file m51.hipparcos:
