3/15/2012If you are creating the pdf of your SJ on a Mac (especially if you use our template), you may find that your top margin is too small. To fix this, edit the line: \setlength{\voffset}{0n} to read: \setlength{\voffset}{0.7in}
3/13/2012 RPS Constraint and Slew Tax estimator: The slew tax and constraint counts in RPS are determined based on the number of observations, defined to have maximum length of 80 ksec, rather than targets. The actual accounting at the Peer Review will be based on 90 ksec observations.
12/15/2011 The Cycle 14 Call for Proposals and Proposers' Observatory Guide have been Released.
