This paper presents new trigonometric parallaxes and proper motions for 214 stars. The measurements were made at the US Naval Observatory Flagstaff Station (NOFS) between 1989 and 2017, and the average uncertainty in the parallax values is 0.6 mas. W

We present a set of 58 stars with JHK standard values on the CIT system and with a suitable magnitude range for use with array detectors on small- to moderate-size telescopes. Each final value is based on six to 47 measures (with a mean of 17) obtain

Trigonometric parallaxes have been measured by Dahn et al. (2002) for 28 cool dwarfs and brown dwarfs, including 17 L dwarfs and three T dwarfs. Broadband CCD and near-IR photometry (VRIz*JHK) have been obtained for these objects and for 24 additiona
