Agenda:

1. News on core extraction 

Not discussed today

1. Mass estimates (WG led by Alex & Fred)

• Jeff evaluated the filtering scales of each image using MnGSeg
  
  

* Max recov. scale = ~0.6 x \lambda/Lmin         See equation nº6.1 (p53) in https://www.iram.fr/IRAMFR/ARC/documents/cycle1/alma-technical-handbook.pdf

Jeff will circulate his presentation so that everybody can judge if this methodology can be validated and used for our whole dataset. He will apply it to BOLOCAM images.

• News from Alex by email
  

• I have been able to run PPMAP with just the Herschel bands, and at 14 arcsecond (7 arcsec pixel) resolution. It fits beautifully, and gives a temperature map consistent with the high resolution one. 
  

• I have also been able to filter the Herschel images to both 60" and 30" (60 just so it isnt so harsh, 30 as the max scale size across all bands) and will run those models soon (today/tomorrow).
  

• Free-free contamination level from H41a images.
  

    Not discussed.

1. First CMF results

Not discussed.
