Calibration

Looks fine in general.

Step 19. hif_applycal: there is a warning/note--Phase vs frequency outliers. See plot below (toward the phase calibrator J1744, SPW 35 for EB uid___A002_Xfddca6_Xe2c.ms). I don't how this could happen or if it causes any problem.

Continuum imaging

Looks good.

Step 31. hif_findcont: status shows 'OLD', but based on the plots in step 38, the continuum identification is ok in general. SPWs 29 and 31 may include some lines in the 'line-free' frequency ranges.
The image shows a single source. Beam size is ok: 1.56 x 1.02 arcsec

Line imaging

Size mitigation: SPW33 was size-mitigated. All the other SPWs used nbins=2.
The largest beam size is found for SPW31: 2.02 x 1.31 arcsec (geometric mean = 1.63 arcsec)
Interesting map from SPW31 (HNCO). This field is on the south-eastern corner of the whole coverage.

Hipergator pipeline run line imaging

It seems that the size mitigation problem has been solved in this pipeline run. However, although the final images exist in Globus, the weblog doesn't report anything. I will download the images from Globus and check them.

xinglunju commented 1 year ago

Update

I don't find any image products in Globus produced by the hipergator pipeline run. The imaging should have failed and only left behind some intermediate products Since the hipergator imaging pipeline already has all the parameters for solving the size-mitigation issue, we may simply re-run it, as long as it can run to the end and produce the images. Is there such a way? @keflavich

@keflavich SPW33 has the correct cube size (3840 channels), and there is an overwrite argument in the json file. The other SPWs are 2x binned.

keflavich commented 1 year ago

for the non-spw33 bands, are the override_json commands correct?

xinglunju commented 1 year ago

One more question... should I keep the override command for SPW33 in the json file, or delete it (since it has been run and the image is available)?

keflavich commented 1 year ago

keep it. These commands are our central record of what has been done.

xinglunju commented 1 year ago

The spw33 cube in globus looks great. The other spws are still 2x binned, and are probably still undergoing re-clean.

keflavich commented 1 year ago

Moved unmitigated cubes to unmitigated/ directory. spw33 was OK, but the others need reimaging, as @xinglunju notes. Reimaging will happen shortly.

xinglunju commented 1 year ago

Mar 1 2023 update: SPW33 has been unbinned and the cube looks good. Cubes of the other 5 SPWs are still 2x binned on Globus. @keflavich

keflavich commented 1 year ago

Yep. Looks like I managed to move the scripts to the unmitigated directory, not the cubes. Oops. Fixed now

xinglunju commented 1 year ago

All cubes look good. Marking this one as done.

A potentially interesting source:

The coordinate is roughly 17:48:18.512, -28:19:48.219

Seen as point-like absorption in all SPWs. Nothing can be found on SIMBAD catalogs. Could be a quasar??

The only emission is in SPW33, at ~99 GHz, which could be H40 alpha. The emission is also point-source-like, centered on this source.

Spectra of the six SPWs:

xinglunju commented 1 year ago

Update on that source:

No ACES 3mm continuum emission at this position.
Assuming the line emission H40alpha, its Vlsr is at ~100 km/s.

djeff1887 commented 6 months ago

Cont QA (spw25_27,spw33_35): some line contamination in 25_27, minimal in 33_35.

djeff1887 commented 4 months ago

(upper 25_27, lower 33_35) 25_27 has improved, but 33_35 has definitely gotten worse. Not sure why, but there's clearly a lot more line contamination here. And the common bright source is now missing from the image and the residual.

keflavich commented 4 months ago

We'll need to look into this one more - a bright source present in one sideband but not the other is likely an indication of contamination. Let's look at the continuum selection figures and check out the spectrum of that source.

keflavich commented 3 months ago

The bright source is real, GPSR5 0.824-0.190, and has a whopping bright H40a recombination line and even an H50beta line. The continuum source is 30 mJy!

So the missing continuum is an indication of failed imaging. uid___A001_X15a0_X166 s38_0 Sgr_A_star_sci spw33 cube I iter1 image-Z-Profile-Region_Cursor-Statistic_Sum-Coordinate_Current}-2024-05-20-11-27-29

keflavich commented 3 months ago

Removed bad images: mv *.spw33_35.* failed_20240520/ mv *.spw25_27_29* failed_20240520/

I will restart with identical parameters and hope the redo fixes the problem. If it does not, we may need further investigation - possibly this is caused by an incorrect data column selection as we recently saw in aj, p, & v (https://github.com/ACES-CMZ/reduction_ACES/issues/235#issuecomment-2120637880)

keflavich commented 3 months ago

spw33_35 is restored

full aggregate is still cleaning
