Description
We have constructed a sample of M dwarfs out to a distance of ~100pc. This sample of 605 stars (574 M dwarfs and 31 K dwarfs) have been spectroscopically observed, yielding spectral types, radial velocities, H{alpha} equivalent widths, and molecular band indices. Photometric observations have been compiled, with photographic plates providing RI magnitudes and JHKs magnitudes from Two Micron All Sky Survey (Cat. <II/246>) observations. Proper motions were determined by a match to USNO-B (Cat. <I/284>), and distances were computed employing a spectroscopic parallax, allowing the computation of UVW space motions.
