[mmaimcal] [Almasci_chile] Some thoughts on ALMA calibrator sources

[Al Wootten]

Hi Anita

There is a wiki for discussion of the development of requirements for a 
calibrator database.  It should be a framework for pushing the 
discussion along--Jeff updated it in June of last year.

http://almasw.hq.eso.org/almasw/bin/view/Archive/AsaCatalogues

I'd suggest that to be a good place to put your draft for discussion.

The science group task assignments are at:
http://wikis.alma.cl/bin/view/AIV/ScienceGroupTaskAssignments
It looks like Stuartt is in SCO this week; you could chat with him and 
Richard and Rudiger, I'd suggest.

Clear skies,
Al
