This looks fine -- cubes just need to be re-cleaned at native spectral resolution. There's a bit of phase and amplitude spread in one of the later scans, but this is minor. Beam is a bit elongated again (ratio ~ 1.6), but not too bad.

I think this is good-to-go once the cubes have been recleaned at full resolution.

@keflavich channel parameters have been updated in #302. Once merged, this region will need to be recleaned to get the cubes at native resolution.

moved files to cubes_pre20221118 and started new run for spw{25,27,29,31,35}

d-l-walker commented 1 year ago

Cubes have successfully been re-imaged at native spectral resolution and look OK -- marking as done.

Hmm, it seems that SPW 33 may still be size mitigated for this one. In the override_teclean_commands.json, all SPWs have their channel numbers explicitly defined, whereas SPW 33 has nchan: -1. This should not result in a size mitigated cube, but that seems to be the case ...

@keflavich can you verify that this cube is size mitigated? Looking on globus the file size is ~ 0.5x the size of the SPW 35 cube, so it seems likely.

(Tagging #179 for tracking)

@keflavich - just needs to be rerun...

QA - Line contamination in continuum images from high/low frequencies

Possible line contamination in spw25_27. Otherwise, the images look good.

Further checking the mfs images and cubes. The mfs images of spw 25 and 27 both look good. The spw25/27 cubes show lines with similar morphology to the contamination feature in spw25_27 continuum image, suggesting findcont issues.

Updated continuum QA (20240403)

The images look good. The line contamination in spw25_27 is gone.
