rascil_advise

rascil_advise is a command line app written using RASCIL. It provides advice on imaging parameters for a CASA MeasurementSet.

Example script

The following provides advice on an MS generated by the MID continuum imaging simulations:

#!/bin/bash
# Run this in the directory containing SKA_MID_SIM_custom_B2_dec_-45.0_nominal_nchan100_nominal.ms
python3 $RASCIL/rascil/apps/rascil_advise.py --ingest_msname SKA_MID_SIM_custom_B2_dec_-45.0_nominal_nchan100_nominal.ms

Command line arguments

                     [--ingest_dd [INGEST_DD ...]] [--logfile LOGFILE]
                     [--guard_band_image GUARD_BAND_IMAGE]
