CorMASS+Magellan
• CorMASS– Instrument team = John Wilson, Mike Skrutskie (UVa)– Capabilities = 0.8-2.5 m, cross-dispersed, R=300, f/9– Previous telescopes = Palomar 60”, VATT, APO 3.5 m– On Magellan = 0.4x3” slit, SN=10 for K=18 in 1 hour– Ideal for followup of candidate brown dwarfs

• Observing run on Magellan– ~8 nights in February or March 2005– Queue observing for IRAC targets and other CfA proposed
work– Harvard-only run now, but will advertise to partners up
