Table 1: Basic and derived data for observed targets. The abbreviated name Dnnnn will be used throughout this paper. Co-ordinates are Equinox J2000 and are given in unabbreviated form. Previously known objects are referenced in the final column. IJK magnitudes are from the DENIS database and have typical errors 0.05-0.1 mag. The modified Julian date of the DENIS observation, galactic latitudes, derived spectral types and distances are given in Cols. 6-9. Spectral types quoted are the mean of those derived from independent K- and H-band derivations, where both are available (see Col. 10). For 2MJ1112, the I-band magnitude is from UKST/SuperCosmos¹; JK from 2MASS.
Table 2: The nearest L-dwarfs to the Sun, ordered by distance. Where distances are measured from a parallax determination, this is indicated. Otherwise, distances are based on current calibrations and have been obtained from the literature. Rather few L-dwarfs have been found within $\sim$ 10 pc and this work increases the known database of such objects by $\sim$ 25%.
Table 3: Proper motions for the target objects derived from SuperCosmos and 2MASS positions with the epoch difference indicated. For typical positional errors $\sim$ 0.3 $^{\prime \prime }$ , uncertainties on the proper motions are therefore $\sim$ 100 mas yr^-1, for $\Delta _{\rm epoch}$ = 4 yr. Transverse velocities are derived using the distances in Table 1 and the proper motion values, added in quadrature.
