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
