Some useful sources of data on L and T dwarfs

  • DwarfArchives.org
  • Adam Burgasser's T Dwarf page
  • Kirkpatrick Spectral Archive
  • Sandy Leggett's data
  • Adam Burrows
  • Ian McLean's NIRPSEC Spectroscopic Survey

    Other issues

  • Expected numbers of L and T dwarfs as a function of J mag.
  • Expected numbers of z>6,6.5,7.0,7.5,8.0 quasars as a function of J mag.
  • distinguishing QSA, L and Ts.
  • proper motions as a discriminant
  • Methane filters are a useful L/T discrimant; may not be useful for quasars
