Astronomy and Photometry for ~1000 L, T, and Y Dwarfs from the UKIRT Hemisphere Survey (Schneider A. et al., 2023AJ, 166, 103)
From the UHS, UKIRT has ascertained the positions, photometry and proper motions for 966 known Brown Dwarfs. The measured proper motions are more precise than those from CatWISE and Pan-STARRS, but not Gaia – a valuable resource for non-Gaia point sources. The figure below is a comparison between the proper motion measurements and those from Gaia, CatWISE, and Pan-STARRS.
