Notes: UKIDSS magnitude limits for Y, J, H and K bands are 20.5, 20.0, 18.8 and 18.4 respectively. All magnitudes here are Vega based. We use 0.1 $^{\prime\prime}$ as a typical position error for UKIDSS. Error ellipses of 2MASS and SDSS overlap for some objects for which proper motion angle errors are not listed; a spectral types are based on the relationship between spectral type and SDSS and 2MASS colors (i-z, i-J, i-H, i-K are used largely and r-i, z-J, z-H, z-K with less weight); b It is merged with a nearby faint galaxy in 2MASS image, so its 2MASS photometric data is not reliable. The spectral type is based on SDSS-UKIDSS colors (i-J, i-H and i-K) according to Eq. (9). c Data errors of J, H, K bands are less than 0.005.
