Abstract:
Using the Position and Proper Motion Extended-L (PPMXL) catalogue, we
have used optical and near-infrared colour cuts together with a
reduced proper motion cut to find bright M dwarfs for future exoplanet
transit studies. PPMXL's low proper motion uncertainties allow us to
probe down to smaller proper motions than previous similar studies. We
have combined unique objects found with this method to that of
previous work to produce 8479 K<9 M dwarfs. Low-resolution
spectroscopy was obtained of a sample of the objects found using this
selection method to gain statistics on their spectral type and
physical properties. Results show a spectral-type range of K7-M4V.
This catalogue is the most complete collection of K<9 M dwarfs
currently available and is made available here.

1 = one of the coordinates had an excessively large χ2
2 = row from PPMX (Cat. I/312) [if set, magnitudes b1, b2, r1, r2, i
have a special meaning]
10 = row from PPMX (Cat. I/312) [if set, magnitudes b1, b2, r1, r2, i
