Sept. 18, 2008SLUO 2008 Annual Meeting Access to LSST Data and the LSST Science Collaborations *All raw data and derived data products will be publicly available as soon as they are generated. –Data Access Centers (a la′ ATLAS Tier 2 Data Center) *Data management to support a wide range of queries. –From a junior high school student looking for images of stars and galaxies, to a large professional science collaboration wanting routine access to the entire data volume. *The LSST Construction Project is not designed or intended to be the organization that delivers LSST science. *To secure LSST science, we have formed semi-autonomous LSST Science Collaborations.

Sept. 18, 2008SLUO 2008 Annual Meeting LSST Science Collaborations

Sept. 18, 2008SLUO 2008 Annual Meeting Roles and Responsibilities of LSST Science Collaborations *Organization and management – spokespersons, membership decisions, science coordinators, publication policies, speaker boards, etc... *Activities and deliverables of Science Collaborations. –Develop and document LSST science analyses. –Provide input to LSST final design and survey strategy. –Develop and participate in precursor studies. –Deliver first-year commissioning science targets. The present project plan is for “first light” in 2014, and survey and science commissioning in We expect this to lead to first publications. *LSST Science Book (2009 Edition)
