siras Examples

Example 1. Search with results to standard output

Find the 10 brightest IRAS Point Source Catalog Stars in 1 degree square box centered on 10:00:00 +30:00:00 J2000 and sort them by magnitude.

siras -hn 10 -r -1800 10:00:00 +30:00:00 J2000

produces the following:

Example 2. Search with results to a file

Find all IRAS Point Source Catalog stars within 40 arcminutes of M51 and write the results to a file

siras -wts -r -r 2400 -o m51 13:27:48.311 +47:27:28.98 B1950

produces the following in the file m51.iras:

Example 5. Match stars in input catalog

Match the stars in the input catalog test.tab to the IRAS Point Source Catalog and list them one match per line.

siras -l @test.tab

produces the following:
