Pointing Offset Calibration

The pointing-offset chart runs the pointing offset calibration pipeline. This fits primary beams to cross-correlation visibilities to estimate pointing offsets.

For full details of this pipeline see its GitLab repository

The chart currently runs a Kubernetes Job - but this may change!
