Agenda:

1. Draft of Website for ALMA-IMF (Fab)
   

1. Debrief on the ALMA-IMF workshop (22 to 26 of March)

Draft schedule
2:00 - 2:10: Fabien (global CMF)
2:10 - 2:20: Mélanie (G012)
2:20 - 2:30: Xing (G327)
2:30 - 2:40: Hideaki (G338)
2:40 - 2:50: Yohan (W43-MM2&3)
2:50 - 3:00: Nichol (MnGseg catalogs)
3:00 - 3:10: Theo (protostellar + core models)
3:10 - 3:20: Pierre (PPMAP and Herbie)
3:20 - 3:30: Synthesis: Identifying common tools and objectives

-> coming back on the CMFs in W43-MM2&3 (Yohan)

Questions:

• Error bars on the CMF; how different from Salpeter in the end?
  
  • both on the data and on the slope fit
    
• Temperature: how drastic is the change with/without PPMAP estimations?
  
• Pre versus proto: how do you pinpoint hot cores?
  
• How is done the evaluation of completeness?
  

1. A word on the outflows, what is the status?
   • Sylvain ?
     

-> Maxime is handling the code; need to compare the different methods; implementing the PA detection & removing the contamination from nearby sources. Final goal: search massive prestellar core candidates

• Thomas ?
  

-> Almost on final state in MM2&3 ; ~50 cores with outflows. The idea is to present them (CO only), no hot-core information. (+perhaps MM1 for statistical reasons: 50 cores is insufficient to derive accurately a core mass function)

• Allison ?
  

-> need to get in touch with Thomas to compare the results btw SiO and CO. Ideally a catalogue of the outflows for ALMA-IMF fields ; any evolution with the evolutionary stages ; episodic ejection ?

-> Try and build global pre/proto-stellar CMFs? Search if SiO outflow is an effect of core-mass or of environmental density
