Notes. The ‘Name’ column corresponds to the SHORTNAME in the GUCD catalogue. The uncertainties of a0 were computed using linear error propagation. The three additional sources at the bottom of the table are the reddest OrbitalTargetedSearch sources at the bottom of the main sequence, which are not in the GUCD catalogue.
