System Status Reviews
Minutes to the December 3, 2003 Status Review Meeting. This meeting which was the first of several was intended to provide background for the current status of Fly-Eyes wavefront sensor demonstrator development.
Minutes to the January 26, 2004 Dewar Status Review Meeting. This summary is a review of a visit to IfA and GL Scientific to review the dewar contract with Gerry Luppino and to discuss the state of bimorph mirror development with Christ Ftacles.
Minutes to the March 1, 2004 Fly Eyes Review Meeting. A continuation on the status of Fly-Eyes wavefront sensor demonstrator development. A list of Action items follows:
MeetingsMinutes to the Requirement Summary meeting of September 29, 2003. This meeting was an organizational meeting identifying the systems that would likely need upgrading to obtain the required performance for Pueo-Nui. Several proposals were also identified.
Minutes to the December 5, 2003 Planning Meeting. This meeting layed the foundation of the scope and goals of the Pueo-Nui project. It also identified issues to be addressed and those which will not be addressed. A list of actions were prepared with proposed time frames for completion of actions.
