APOGEE KM Dwarf Catalog
My collaborators and I put together a sample of nearly 4000 late-K and early-M dwarfs that have stellar parameters in the SDSS ASPCAP catalog. For convenience, I've put a fits table of the APOGEE KM catalog available in a Github repository.
BOSS Ultracool Dwarf Catalog
In the BUD project, we are characterizing a sample of over 13000 ultracool dwarfs with SDSS spectroscopy and SDSS-2MASS-WISE photometry. The fits table of the BUD catalog is in a Github repository for easy access, and should also be available as a download with the published article.
SDSS L dwarf Templates
As described by Schmidt et al. (2014), these optical spectroscopic templates of L0-L8 dwarfs are appropriate as spectral type and radial velocity standards. The templates can be found either on Github or on Suzanne Hawley's webpage.
