Notes. (a)SpT-PHOT combined spectral typing and photometric data; SED based on SED model-fit; SPEC spectra-library fit to spectra; PHOT fit of photometric data to models using MCMC or Bayesian methods. (b)Spectral types may be reported as a range with two MK SpTs separated by a symbol -. Unresolved multiple systems may have each components’ spectral types reported separated by a symbol +. (c)Extra information on the spectral typing reported by the original study. For example, luminosity classes are reported if available and emission spectra will include a flag e.
