Notes from session

Notes from Steve Allen's talk:

  • 1 arcminute resolution provides an enormous increase in cluster discovery potential relative to 3 arcminutes
  • 1 arcminute would greatly increase galaxy science, and the size of the community served.

Here is the strawman conversion between size of telescope and FWHM as a function of channel that Mat and Nick were looking at (from Darcy/Mike). Just a strawman. Tel size.png

(Jo is also taking notes, will paste after session!)
