sppm Examples

Example 1. Search with results to standard output

Find the 10 brightest PPM Catalog Stars in 1-degree square box centered on 10:00:00 +30:00:00 J2000 and sort them by magnitude.
sppm -hn 10 -r -1800 10:00:00 +30:00:00 J2000
produces the following: 
sppm WCSTools 3.6.9, 6 July 2007, Doug Mink SAO

Example 2. Search with results to a file

Find all PPM Catalog stars within 40 arcminutes of M51 and write the results, sorted by right ascension, to a Starbase file
sppm -wstr 2400 -o m51 13:27:48.311 +47:27:28.98 B1950
produces the following in the file m51.ppm:

Example 5. Match stars in input catalog

Match the stars in the input catalog test.tab to the PPM Catalog and list them one match per line.
sppm -l @test.tab
produces the following:

where the columns are input catalog star name, RA, Dec, magnitude, spectral type, PPM number, RA, Dec, magnitude, number of stars in the 5000-arcsec-radius default search radius, and catalog - search dra, ddec, and dr (in arcseconds).
