                                    SDSS (II/294), 2MASS (II/246) and UKIDSS (II/304) photometry of 806
ultra-cool dwarfs. Proper motions are found by dividing the difference
between the 2MASS and UKIDSS coordinates by the observational epoch
difference. Spectral types are based on their SDSS spectra and the
relationship between spectral type and SDSS and 2MASS colors.
