Cormass magellan1
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


Cormass magellan2
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 approval
