ssao Examples

Example 1. Search with results to standard output

Find the 10 brightest SAO Catalog Stars in 1-degree square box centered on 10:00:00 +30:00:00 J2000 and sort them by magnitude.: ssao -hn 10 -r -1800 10:00:00 +30:00:00 J2000
produces the following: ssao WCSTools 3.6.9, 6 July 2007, Doug Mink SAO SAO 10:00:00.000 +30:00:00.00 J2000 +- +00:34:38.5 +00:30:00.0 at epoch 2000.0000 SAO 09:57:06.660 +30:14:24.47 B1950 +- +00:34:38.5 +00:30:00.0 at epoch 1950.0000 SAO_number RA2000 Dec2000 Mag Type Arcsec 081129 09:59:36.254 +29:38:42.96 5.90 K0 1313.89 061791 09:59:07.038 +30:25:18.62 8.00 K0 1666.59 081121 09:58:29.735 +29:32:04.36 8.20 K0 2046.73 061783 09:58:19.185 +29:55:34.15 8.50 __ 1336.81 061796 09:59:15.801 +29:52:46.21 8.80 __ 719.89 061795 09:59:15.132 +30:15:23.79 8.80 __ 1091.89 061799 09:59:19.837 +30:00:27.46 8.90 __ 522.44 061807 10:00:52.169 +30:12:16.24 8.90 __ 1000.18 061786 09:58:33.478 +30:17:12.45 9.30 __ 1524.98

Example 2. Search with results to a file

Find all SAO Catalog stars within 40 arcminutes of M51 and write the results, sorted by right ascension, to a file: ssao -thws r -r -2400 -o m51 13:27:48.311 +47:27:28.98 B1950
produces the following in the file m51.sao: catalog SAO ra 13:27:48.311 dec +47:27:28.98 radecsys fk4 equinox 1950.0000 epoch 1950.0000 rpmunit mas/year dpmunit mas/year drasec 2400.00 ddecsec 2400.00 catsort ra program ssao WCSTools 3.6.9, 6 July 2007, Doug Mink SAO sao_id ra1950 dec1950 mag type pmra pmdec arcsec ------ ------------ ------------ ----- ---- ------ ------ ------ 044612 13:24:29.303 +47:40:59.83 8.80 __ 1.0 -58.0 2171.09 044614 13:25:10.907 +47:04:43.11 8.60 __ -58.2 48.0 2105.32 044617 13:25:39.289 +48:01:05.11 8.20 K0 12.0 -43.0 2399.74 044625 13:26:55.843 +48:06:18.44 7.10 F5 -51.1 4.0 2388.73 044635 13:28:56.396 +47:57:56.45 8.80 __ -38.2 -31.0 1952.39 044642 13:29:50.239 +47:29:28.37 6.90 A5 30.4 -6.0 1241.95 044653 13:31:08.164 +48:00:55.87 7.60 K0 7.0 -21.0 2844.68 044658 13:31:28.339 +47:03:09.29 8.50 __ 30.7 6.0 2673.69

Example 3. Find closest star

Find the closest SAO Catalog Star to 10:00:00 +10:00:00 B1950.: ssao -a 10:00:00 +10:00:00 B1950
produces the following: 098915 09:59:47.358 +10:10:49.46 8.60 __ 675.76

Example 4. List selected stars from catalog

List SAO Catalog stars 100001 through 100010: ssao -h 100001-100010

Example 5. Match stars in input catalog

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

ssao -l @test.tab

produces the following:
