| - | ====== Planning pointing observations with spec_plan ====== | ||
| - | |||
| - | Currently, this is working on ops4. | ||
| - | |||
| - | Example input files are currently in the home directory: | ||
| - | - x_band_12m_cals.txt : example source catalogue | ||
| - | - boresol_ke.txt : example boresight (pointing) solutions list | ||
| - | |||
| - | Example usage: | ||
| - | <code>/usr2/st/bin/spec_plan2.pl -c x_band_12m_cals.txt -b boresol_ke.txt -a Ho<code> | ||
| - | where ''-c'' refers to the source catalogue, ''-b'' is the list of pointing solutions and ''-a'' is the antenna/site you're observing from. The input files listed above are currently in the home directory of ops4 as an example. | ||
| - | |||
| - | A PGPLOT window will start up showing how the sky looks at the moment. Green triangles indictae calibration sources (the bigger the triangle the brighter the source). Moving the cursor close to a source of interest and pressing ''c'' will tell you the name and coordinates of the source. Press ''h'' to get a full list of options. The grey ''+'' symbols show where pointing solutions have been found recently. | ||

| - | ===== File formats ===== | ||
| - | ==== Calibrator sources ==== | ||
| - | For each new source, the first line should be the RA, Dec (J2000) and Source name. Subsequent lines should be the (same) source name followed by the flux density in mJy. e.g: | ||
| - | <code> | ||
| - | 13:46:49.0432 -60:24:29.354 1343-60 | ||
| - | 1343-60 6000 | ||
| - | 21:57:05.9805 -69:41:23.685 2153-69 | ||
| - | 2153-69 6000 | ||
| - | 22:53:57.7 +16:08:54 3C454.3 | ||
| - | 3C454.3 10000 | ||
| - | 09:45:07.8 +07:39:09 3C227 | ||
| - | 3C227 2000 | ||
| - | 12:28:17.6 +12:40:02 Virgo | ||
| - | Virgo 48000 | ||

| - | ==== pointing solutions ==== | ||
| - | Two possible file formats can be used and the script will automatically determine which one it is. Format 1 is: | ||
| - | <code>Day_number Source_name Az_during_observation El_during_observation El_pointing_offset cross-El_poinitng_offset</code> | ||
| - | |||
| - | Format 2 is: | ||
| - | <code>Day_number Source_name Az_at_start_of_observation El_at_start_of_observation Az_at_end_of_observation El_at_end_of_observation El_pointing_offset cross-El_poinitng_offset</code> | ||
| - | |||
| - | Here's an example of a Format 1 file: | ||
| - | <code> | ||
| - | 158 taurusA 6.9 53.7 0.02 -0.035 | ||
| - | 158 0537-441 -183.6 60.6 0.06 -0.02 | ||
| - | 158 hydraA 94 28 0.03 -0.1 | ||
| - | 158 hydraA 92 46 0.03 -0.07 | ||
| - | 158 0537-441 211 53 -0.04 0.06 | ||
| - | 158 hydraA 88 65 0.04 0 | ||
| - | 158 taurusA -42 42 0.02 -0.0625 | ||
