Parallaxes, Proper Motions, and Near-infrared Photometry for 173 L and T Dwarfs from the US Naval Observatory Infrared Astrometry Program

We present near-infrared parallax and proper motion astrometry for 74 L dwarfs and 99 T dwarfs, as single objects or in binary systems, obtained with the ASTROCAM astrometric imager on the USNO, Flagstaff Station 1.55 m telescope over two observing periods. For all 173 objects, the median number of...
