Agenda items: 

• TP combo progress!!  :D  
  
• Rodrigo’s presentation: https://drive.google.com/file/d/1HG4bMdee65cmCTLc-76UWIo9qnwaGg41/view?usp=sharing
  
  • Several discussion points:
    
    • Is there a systematic shift between 7m12m / total power?
      
    • Are there localized shifts?
      
    • (Why) does the moment1 vary more than the moment2?
      
  • Overall combination looks very good
    
  • Difference in the beam size b/w 7m+12m and feather?
    
    • Power spectrum before vs after combination might help
      
    • https://turbustat.readthedocs.io/en/latest/tutorials/statistics/pspec_example.html
      
  • How quick is it?
    
    • <5m, and <1m when the TP is already regrided to the 7m12m dimensions

To do’s: 
→ Possibly feather the W43-MM1 region, see if velocity patterns persist, Nichol to provide 7+12 data
→ Send G353 feathered and 7+12 versions to JF for MnGSeg analysis 
→ AMS to contact BS re:nestfit in G353 as an example, show us how to run?  
→ Did I miss more items??
