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. (1 data file).
