Table 1: Summary of targets and references. Tip-tilt star magnitude and separation to the target based on USNO-A2.0 (Monet et al. 1998). All distances are photometric, based on the relations of Knapp et al. (2004) between the spectral type, and MJ, and MK (except for SDSS J2047), assuming non-binarity.

1 Spectral types from Burgasser et al. (2006a) except for 2MASS J0756, 2MASS J1036 , 2MASS J1626 and SIMP J0136. 2 Target photometry from 2MASS (Skrutskie et al. 2006). 3 Kirkpatrick et al. (2000). 4 Tinney et al. (2005). 5 Gizis (2002). 6 Knapp et al. (2004). 7 Burgasser (2004). 8 Burgasser et al. (2007) 9 The distance is based on the K magnitude only, as the parallax measurement of sdL7 subdwarf revealed a MK similar to the solar-metallicity L7 dwarfs, while the subdwarf is more than 1 magnitude brighter in the J band (Burgasser et al. 2008). 10 Artigau et al. (2006). They report a distance of $6.4\pm 0.4$ pc.
