APO 3.5 m spectra for objects M9 and later. The spectral types are ours, as given in Table 4, except those for the T dwarfs, which are taken from previously published sources as described in the table notes. These targets were chosen from SDSS imaging data to be very red in the SDSS i* − z* color, producing most of the new mid–late L dwarf spectra in our sample. Note that we have not attempted to remove noise spikes such as the one near 6700 Å in SDSS J1716+5537.
