Current Observation Plan 2012

Meeting Objectives Establish science milestones for next 12 – 18 months (papers + authors, new methods, etc.) – Enhance science paper output  science push – Essential for NASA funding and demo power of MCTs Develop plans to solve outstanding issues: – Requirements for photo-z accuracy – Achievement of required photo-z accuracy – Robust photometric measurements (variable PSF) – Replace A963?? Guide star issues. (More) automated pipelines. Establish milestones for delivery of data and science analysis tools to public. – Part of the expectations of a large MCT Generate new ideas…What are we missing? Meet your new colleagues. Have fun in Heidelberg.
