Notes.
The original DENIS coordinates of the target were corrected for the mean offsets of three reference stars around the target with respect to their 2MASS coordinates. The DENIS data were not used for the final proper motion determination.
The DENIS catalogue gives an epoch of 2000.47, whereas according to the DENIS FITS images it is 2001.47.
Spectral index (and corresponding spectral type) as defined in Burgasser et al. (2006).
