Example of a single order from our observations with the Tull high-resolution optical spectrograph (black). Stars are organized by decreasing spectral type from late-B to mid-M. Standard stars are overplotted in blue and have been broadened and shifted to match the measured radial and projected rotational velocities of the substellar host stars in our sample.
