Contour issues
• Need to decide on what to put into database or link to outside URL
• Automatic report generation
– Issues with formatting
• Outside user testing
– Access should be global (any IP) but requires two passwords (Contour
and Keck internet)
• Make decision on Contour by November 23.

Requirements issues
• Forward and backward trace requires putting contents of ScRD,
SRD into database
• Make decision on Contour by November 23
• Gather input for AO & laser requirements version 2.0
– Release as design work completes at start of calendar 2008
