Preliminary QA Summary for Execution Block ID uid://A001/X15a0/X1a4 Sgr_A_st_ar_03_7M

QA Errors Tclean stopped to prevent divergence in both continuum (SPW 24) and cubes (SPW 24,26). Example (SPW 24): uid___A001_X15a0_X1a4 s34_0 Sgr_A_star_sci spw24 mfs I iter1 image sky

Continuum:
34 hif_makeimages (mfs) QA Error tclean stopped to prevent divergence (stop code 5). Field: Sgr_A_star SPW: 24

Cube: 38 hif_makeimages (cube) QA Error tclean stopped to prevent divergence (stop code 5). Field: Sgr_A_star SPW: 24 38 hif_makeimages (cube) QA Error tclean stopped to prevent divergence (stop code 5). Field: Sgr_A_star SPW: 26

QA Warnings These are associated with the low SNR SPWs described above

Continuum Significant structure in residuals (upper image ), deeper clean needed? Mask looks ok (lower image) uid___A001_X15a0_X1a4 s34_0 Sgr_A_star_sci spw16 mfs I iter1 residual sky uid___A001_X15a0_X1a4 s34_0 Sgr_A_star_sci spw16 mfs I iter1 mask sky

Cube Divergence in SPW 24 & 26. Need to download cube to inspect ( as soon as I solve globus personalconnect issue)

mpound commented 2 years ago

In the SPW24 and SPW26 cubes a few channels go wonky in clean. The horizontal pattern shows up various intensity levels. A particularly bad example: member.uid___A001_X15a0_X1a4.Sgr_A_star_sci.spw24.cube.I.pbcor.fits - channel 566 ch566

mpound commented 2 years ago

Reprocessed data still have divergence artifacts in spw 24 around the CS line. Ch ~525-625 and spw 26 around the HC3N line ~ch 1007-1013

mpound commented 1 year ago

These still need to be run with the updated tclean parameters. Latest FITS headers for SPW24 and 26 still show cyclefactor=1.0.

Reclean on SPW 24 & 27 look good. Marking this done.

keflavich commented 1 year ago

Reimaging of this one appears to be running still - so I think the Done label was perhaps added prematurely? If anyone has notes on this field, please add them in. I just had to restart a partially-failed imaging run of spw26.

mpound commented 1 year ago

I must have marked this done prematurely (could have been looking at data from another issue?) The last data I have from Nov 02 still have the artifacts in chanels 1007-1001 in spw26. The reprocessed links above are dead links but don't have "reclean" in their filenames which they would if they came from the merge #248. Removing the done label and move issue back to Under QA.

mpound commented 1 year ago

I am recleaning these locally.

mpound commented 1 year ago

I have verified that the recleaned SPW24 and SPW26 fix the divergence problem. The new files are uid_A001_X15a0_X1a4.s38_0.Sgr_A_starsci.spw26.cube.I.iter1.reclean.image.pbcor.fits and uidA001_X15a0_X1a4.s38_0.Sgr_A_star_sci.spw24.cube.I.iter1.reclean.image.pbcor.fits

Below are differences between to old and new cubes (old minus new) showing where the bad channels were and that other channels were unchanged. Interestingly, there was low level divergence in many channels in the original cube that were not obvious on inspection.
