!! Comments:
!! We assume here that the setup for the continuum backend has already
!! been done earlier and that the pointing is to be done with the
!! continuum backends.  Then the backend commands above achieve that
!! (only) the continuum backends are connected for the pointing.

To execute this script, simply enter:

@ demo-pointing

After a pointing the data processing software displays the results and you can enter a correction for the observed pointing offsets with the command

SET POINTING azimuthCorrection elevationCorrection
