1 UKIDSS passbands as described in Hewett et al. (2006). 2 H- and K-band photometry were obtained on a single night. The photometric errors were calculated using a 5% error from the nearby 2MASS star used for flux calibration, a 2-3% photometric measurement error, and an assumed 5% internal error typical of near-infrared arrays. The final column displays the nearby 2MASS calibration star with its 2MASS catalogue photometry and errors. Colour transformations between the filters are of the order of 1% (Carpenter 2001) and so are neglected.
