Produce deconvolved images around each spectral line available in the CATALOG and covered by the frequency setup. Continuum emission is (empirically) separated from Line emission using the UV_PREVIEW, UV_BASELINE / UV_FILTER mechanism, and the continuum images are also produced.
This step does not use the result of the PIPELINE TABLES step, but only the self-calibrated UV tables produced by PIPELINE APPLY and PIPELINE TIME.
This is Step 9, NEXT step is SHOW
