Meeting ID: 927 5610 3231
Password: 9Jfuq5

Attendees: Nathalie, Ana, Hongli, Adam, Allison, Amy, Mélisse, Timea, Fred (late)
Not attending: 
Document drafted by Timea, but feel free to add notes

Agenda:
  1. Current issues and limitations with line/cube cleaning
  • Status of pipeline processing of cubes
  • are there any new cubes available?
    • > previous issues with frequencies, velocities etc. resolved
    • still on auto multi-thresh
    • some issues: baselines/slopes
  • what shall we look at first as QA? (which lines, which spw?)
    • check what data product exists
    • distribute the fields
  • Auto-correlation issue: FAUST home-made script to be run after the regular ALMA calibration pipeline to correct for this does exists, Adam is going to contact the PIs

  • Contribution to cubes QA 
Roberto on the H41a cubes, result of re-running them with new parameters in Morelia?
-> PSF issues
Mélisse did the QA for G337 cubes (full spw)
https://docs.google.com/document/d/1TA7FLMqnHI4CU6K-h0WOGnAyVRONuZAwqPjiFxSKUgE/edit?usp=sharing
  1. Status of on-going projects
  • Antoine: Melanie (PhD) on shocks
  • Manuel+Estrella
  • LAB: 
    • Melisse on G337:
  • Line identification towards G337-MM1 is done (only a few lines remain unidentified in both B3&B6)
  • Compare molecular content with other positions towards G337
  • QA for G337 showed that the  baseline is not so good in continuum-subtracted cubes delivered by the pipeline → tests with STATCONT and Jordan’s method to subtract continuum from non-contsub cubes
  • Nathalie W43-MM2


  • Anyone else?
A script to download a bunch of cubes at once using Globus in command line is in:
https://github.com/ALMA-IMF/private-work/tree/master/misc
(Note: to access to /private-work you need to be added by Adam)
  1. Status of data processing tools (ADMIT, IMAGER)
    • Status of the update of the linelist for ADMIT ? 
    • Adam: Linelist  on github + google doc
    https://github.com/ALMA-IMF/hotcores <- place to put line lists, code related to hot cores, etc.  This is private, so you must request access (give Adam your username)
  • spectral-cube tutorial -> Who would be interested?
    • Manuel, Fabrice, Melisse, Ana -> see with Adam

Meeting ID: 927 5610 3231

Attendees: Timea, Nathalie, Sylvain, Fred, Mélisse
Not attending: 
Document drafted by Timea, but feel free to add notes

Agenda:
  1. Current issues and limitations with line/cube cleaning
  • Status of pipeline processing of cubes
- Using the continuum image as a start model for cleaning non-contsub cubes is now implemented into the pipeline. Have cubes been made using this feature?
     - only W51 test case has been started and has not been finished.
    - this is new, so the cubes already done and available on globus are probably not yet done with this new feature

- There are some recent changes to the default autoMT params in the pipeline, mainly from Manuel’s suggestions. Some of these suggestions were implemented into the defaults but some were not. See discussion in slack #lines and in the repository: 
https://github.com/ALMA-IMF/reduction/commit/330b345c2913ed851a21a5900dd09d2102a1a281
These changes are expected to make more efficient the cleaning of cubes with extended emission, but at least for the recomb lines I am returning to the params that create tighter masks. That can be done on a per-source basis in imaging_parameters.py, e.g., 
line_imaging_parameters_custom = {
    "G008.67_B3_12M_robust0_contsub": {
       "minbeamfrac": 0.3,
       "dogrowprune": True,
       "threshold": "5mJy"
    },
    "G010.62_B3_12M_robust0_contsub": {
       "minbeamfrac": 0.3,
       "dogrowprune": True,
       "threshold": "8mJy"
    },
    "G012.80_B3_12M_robust0_contsub": {
       "minbeamfrac": 0.3,
       "dogrowprune": True,
       "threshold": "12mJy"
    },
  • Contribution to cubes QA 
Roberto did the QA of a few of the H41a cubes in Florida: 
https://docs.google.com/document/d/1-opjb6RU_4W-C_5gzld0UFn9_V-lYm_DN8fsgVIzl1U/edit?usp=sharing
and with that info is re-running them in Morelia 

  1. Status of on-going projects
  • Antoine: Melanie (PhD) on shocks
  • Manuel+Estrella: 
            status of the data? -> QA on W51
            status of the project?
  • LAB: 
    • Melisse on G337: 
      • line identification done (B3+B6) towards G337-MM1
      • B6 one spw1 missing? (Adam is going to look into it) 
    • Nathalie W43-MM2: 


  • Anyone else?
A script to download a bunch of cubes at once using Globus in command line is in:
