    Cluster group,

    This is a reminder of the conference call on the Cycle 15 proposal:
    Thursday Jan 12 at 10 AM PST.
    Toll Free: 1-866-801-6995, Toll (for International callers):
    1-517-466-6421
    Participant Pass code: 112316

    LBL group: we'll meet in 50B-4205.

    Please check the directory for the latest draft
    http://supernova.lbl.gov/HSTclusterSN/proposals/HSTc15/clusters/text/
    As of this e-mail, changes have been made only to the Descriptions of
    Observations section. There may be additional changes before the call.

    Note that STSci has decreased the page limits for cycle 15 to 11 pages
    total:
    % There are page limits on the size of your PDF attachment.
    %
    % For Large GO proposals, Treasury GO proposals the page limits
    are:
    % - No more than 11 pages total.
    % - Any text in the `Scientific Justification' section,
    % may not extend beyond page 6.

    The 6p limit for sci just is the same as last year (and our text
    saturated that limit). They've eliminated the 2-gyro and results from
    previous programs sections. As it stands, we need to cut about 1.5p
    from the total, which can come from any section of text or figures.

    -Tony
