Summary

I'd recommend setting this as "Done". There's one minor issue for SPW 29 (see below), but that's it.

No major issues to report.
Continuum looks pretty empty. No action needed, just making a note.
Several SiO masers in SPW 25 again.
Velocity shift has worked nicely:

Old SPW 31 spectrum (wrong velocity shift)

New SPW 31 spectrum (updated velocity shift)

There is still some residual emission in the line-free moment 8 map for SPW 29. This is likely due to some line-emission being included in the continuum channels:

Not major issue, but more continuum could be found.

The beam sizes are a bit large:

for the aggregate continuum image: 2.03 x 1.70 arcsec.
for the cubes: between 1.95 x 1.65 arcsec (the two wide windows in the upper sideband) and 2.50 x 2.13 arcsec (the four narrower windows in the lower sideband).

Running into trouble with continuum imaging:

2024-04-02 02:28:03     SEVERE  tclean::::casa  Exception Reported: Error in tclean: Error in making PSF : Imaging weight calculation is requested for a data that was not selected

Not sure what this means yet. Taking notes.

keflavich commented 6 months ago

Just for the record, our selection is fairly large: so it doesn't seem likely that the selection itself is at fault.
