Everything looks good with this one. All cubes were binned x2 for size mitigation. I'll leave this one as 'Under QA' until this is resolved.

One thing to note is that the HCO+ emission is cut off at the lower edge of the window. As far as I can tell, no velocity shift was requested for this SB.

[d-l-walker]

@keflavich now that #287 has been merged, this region will need to be re-cleaned with the updated parameters to get the full cube resolution.

[keflavich]

moved all old files to mitigated_old/ subdirectory. Re-imaging will trigger soon.

[d-l-walker]

@keflavich just checking up on this one, and it looks like SPW 33 has been cleaned at full spectral resolution, but all other SPWs only have the size-mitigated products still?

[keflavich]

Could you verify that the unmitigated sizes are appropriately specified in override_tclean_commands?

[d-l-walker]

Yep, they're all there. I added them in PR #232. But when I checked on globus I noticed that the FITS cubes looked suspiciously small. So I downloaded a couple, and they still have the mitigated number of channels (but SPW 33 is fine).

[keflavich]

OK, moved them to pre_mar1_2023 and triggered imaging.

[d-l-walker]

All SPWs have now been imaged at full spectral resolution. The moment maps look good, but I'm going to download and inspect the cubes just to be sure. Assuming all is good, I will mark this as done.

Cont QA (spw25_27, spw33_35): Seems ok, maybe slight contamination mainly in spw25_27

[djeff1887]

25_27 and 33_35: this seems significantly better than the previous run, the residual is down by a factor of ~2-4, and visually there's only very faint hints of the contamination from before.
