Running the pipeline as standalone

The pointing offset calibration pipeline can be run as a stand-alone pipeline (see pointing_offset_cli). To do this, below are steps to follow to prepare your Measurement Sets:

• Generate one Measurement Set for each scan. For example, if your observation is a 9-point scan, the pipeline expects to process 9 Measurement Sets. If all 9 scans are in a single Measurement Set, CASA task split can be used to split them into separate Measurement Sets.

• The dish pointings should be written into the POINTING sub-table following the MSv2 format. If the user prefers to use the commanded pointings, they should be written into the TARGET column of the POINTING sub-table of each Measurement Set. Alternatively, the commanded pointings relative to the pointing calibrator should be written into the SOURCE_OFFSET column and used with the --use_source_offset_column command line argument. Only one dish pointing option can be requested at a time to be used in the calibration.

To apply a static RFI mask, refer to the Applying static RFI mask section and the output data products are described in the Data products of the pointing pipeline section.
