Description
Get the restoring beam. The returned record has the following fields:
major, minor, positionangle, ra, and dec. The last two are the beam
FWHM in right ascension and declination. All returned fields are
quantities; ie, they are records themselves having
fields called value and unit.
Returns
Record or fail
Example
- include 'imagerpositiontest.g';
- ipt := imagerpositiontest();
- ipt.dotests();
- beam := ipt.beam()
- beam;
[major=[value=0.695572555, unit=arcsec], minor=[value=0.623729467, unit=arcsec],
positionangle=[value=-11.487915, unit=deg], ra=[value=0.626736009, unit=arcsec],
dec=[value=0.69286478, unit=arcsec]]
