---+!! Reduced Focal Anisoplanatism Error Demonstration at Keck

---++ Team
   * Lead: Chris Neyman 
   * Scientific Team: Peter Wizinowich, Rich Dekany, Don Gavel, Brent Ellerbroek(TMT).
   * Software: Kevin Tsubota
   
---++ Goal
This is a proof of concept demonstration identified as a NGAO Detailed Design Risk Reduction task.  It also has potential benefit to existing AO systems at Keck and elsewhere.  Use Cn2 information to reduced Focal Anisoplanatism Error. We will also consider other types of innovative single LGS reconstructors.
