Every DAG or task creates .log, .out and maybe .png files that we want to keep. Also, .last files like tclean.last are often created. These are not necessary but can be usefull for debugging things. I assume that almost all tasks require the Measurement Set (MS). I question what tasks actually modify the MS. run_tclean() defaults to using the corrected datacolumn. Does that mean it is changing this column? The reference to datacolumn is stating which column it should read from, it does not imply any change to the MS. Task07 reference savemodel='datacolumn', this actually modifies the MS.
This document it not complete. I am sure I am missing inputs and perhaps outputs as well.
