  2. LSST Town Hall • 231st meeting of the AAS • 1/10/2018
    Formed by the LSST Project in 2006 with the intent to provide a
    forum to engage the community in interacting with the project
    team and played an essential part in producing the LSST
    Science Book in 2009.
    At this stage, the LSST Project no longer oversees the LSST
    Science Collaborations: they set their own policies for
    admission, governance, publication, etc.
    The only constraint is that their members must have LSST
    data rights.
    Any scientist with LSST data rights, including members of the
    US, and Chilean scientific community and international
    contributors who signed an MOU with LSSTCorp are welcomed
    into the LSST community, including the right to apply to join
    one or more Science Collaborations.
    The Science Collaborations:
    LSST Science Collaborations

    Why join an LSST Science Collaboration?
    A forum to better understand how to prepare for the LSST age.
    All SCs have a direct line of communication with the LSST Project to ask questions
    and make recommendations.
    • Each SC has a DM liaison
    • Regular meetings between LSST Project and SCs’ chairs

    via work on, e.g., SDSS, Deep Fields, DES, ZTF, and HSC
    SUMIRE.
    • We are also gathering critical multiwavelength data for AGN
    studies e.g., X-ray and infrared data in the Deep Drilling
    Fields.
    • Roadmapping to prioritize the most essential preparatory
    tasks.
    • Contributions to science-driven optimization of the LSST
    cadence and observing strategy.
