Meeting ID: 922 7079 2020
Password: 9Jfuq5

Attendees: fab, Nichol, Gemma, Fred , Lee, Mélisse, Tapas,Estrella, Sylvain Bontemps, Adam, Nathalie, Antoine, manuel, Ana
Not attending: B. Lefloch, Roberto
Document drafted by Timea, but feel free to add notes

Agenda:

Status of data processing tools (ADMIT, IMAGER)
- Lee: ADMIT tool: provide initial linelist to work in into the tool.
- Contact Lee if needed to get started
- 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 too, perhaps
Hot core WG page: https://github.com/ALMA-IMF/reduction/wiki/Hot-core-WG

Question to Adam: is this site protected in some way? Can I continue to use it for this purpose or better to move to a Google doc? Adam: this version (https://github.com/ALMA-IMF/hotcores/blob/master/README.md -> https://github.com/ALMA-IMF/hotcores/blob/master/telecon_notes.md ) is private

Status of on-going projects

Manuel+Estrella: current status
- Spectra towards W51E seem to have baseline issues towards some positions (in cubes where the baseline is subtracted) -> this seems to vary from different versions
- How to improve the continuum subtraction?
  - discussion on whether to clean cubes with or without the continuum: easier to do the clean with uvcontsub first
  - Manuel: imcontsub
- Why is the average baseline curved? -> check the different data versions, reminder of a previous issue with Jordan’s field
LAB:
- Melisse (+Timea): presenting on G337: issue with non detection of some species?
- Nathalie: complete the line-list for the following weeks

Current issues and limitations with line/cube cleaning

Cubes: what is the current status?
- https://bio.rc.ufl.edu/secure/adamginsburg/ALMA-IMF/cube_quicklooks
Cubes: how well these will be useable for the most line-rich sources? Any post-processing needed? What softwares/methods will be used for their exploitation?

GLOBUS

It needs a little bit of setup but seems to work. Some concerns about transfer speeds but might depend on endpoint connection. A few notes on installation and download script example available in #imaging slack channel. Other nodes from the DR team could download/upload data as needed.

Agenda:

Main objectives and purpose of this WG.
Planned projects, who is doing what

People working with cubes:
- LAB: Melisse (+Timea), Nathalie
- Manuel+Estrella: first look to general problem (beam, noise, number of channels, extended emission, convergence issues,...).

Overlapping goals between Manuel & co and LAB team: the question is how to handle, focusing on one region? Clear desire to work with cubes. W51e2.

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)
Lee: ADMIT tool: provide initial linelist to work in into the tool.
Tutorial from Lee for the next telecon?
spectral-cube tutorial too, perhaps

Lee: kinematics of the lines? perhaps the topic of other working groups? another common interest of several of us.

People interested in specific lines:
- N2H+, CO, Halpha -> already discussed in the data reduction WG
- Antoine: COMs or any other species to estimate N,n,T
- Temperature measures: CH3OH, CH3CN (+isotopologue), CH3CCH lines should be added as priority?
  - CH3OH: Desmond Jeff (UF): Rotational Diagram modeling (use all transitions for a temperature measurement).
    - this is for full cubes, not to prioritize individual line imaging
  - H2CO may be a nice complementary probe to CH3OH
    - 3(0,3), 3(2,1) and 3(2,2) transitions
  - Cyanopolyynes should be targeted.
  - Gemma (chemistry) (and Patricio -> turbulence, cold sources): Deuterated species (N2D+, DCO+, DCN) + N2H+
  - Fred: SiO, 13CS, DCO+/DCN

interpretation of lines:
- LPENS: hopefully Melanie Armante will begin a PhD in October. aim = constraining the physical properties (N, T, n) and then try to apply shock models when/where applicable on a region tbd. Antoine will attend this telecon.

Roberto: image entire spw’s with auto-multithreshold seems to be possible.
From Molet et al. first line list to be compiled to identify lines for N,n,T modeling
