- minimum task parameters:
- intent (default to 'TARGET')
- spw (defaults to science spws)
- specmode (defaults to 'cube' for 'TARGET', else 'mfs')
- create list of imaging targets with these parameters per target set:
- LSRK spw selection if cont.dat / lines.dat exists
- nbin (if set by hif_checkproductsize)
- gridder ('standard' or 'mosaic')
- start (task parameter if set)
- uvrange (task parameter if set)
- set additional parameters via task interface:
- hm_masking ('centralregion' or 'auto')
- run hif_tclean per imaging target (HPC: one job per calibrator image or parallel=True for tclean for intent='TARGET')
