cds-question@unistra.frdwarf-starssubdwarf-starslate-type-starsastrometryvisible-astronomytrigonometric-parallaxproper-motionsinfrared-photometryphotometrystellar-spectral-typesNew, updated, and/or revised CCD parallaxes determined with the Strand Astrometric Reflector at the Naval Observatory Flagstaff Station are presented. Included are results for 309 late-type dwarf and subdwarf stars observed over the 30+ years that the program operated. For 124 of the stars, parallax determinations from other investigators have already appeared in the literature and we compare the different results. Also included here are new or updated VI photometry on the Johnson-Kron-Cousins system for all but a few of the faintest targets. Together with 2MASS JHK_s_ near-infrared photometry, a sample of absolute magnitude versus color and color versus color diagrams are constructed. Because large proper motion was a prime criterion for targeting the stars, the majority turn out to be either M-type subdwarfs or late M-type dwarfs. The sample also includes 50 dwarf or subdwarf L-type stars, and four T dwarfs. Possible halo subdwarfs are identified in the sample based on tangential velocity, subluminosity, and spectral type. Residuals from the solutions for parallax and proper motion for several stars show evidence of astrometric perturbations.2017AJ....154..147Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/147CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/118 : UBVRI standards around Celestial Equator (Landolt 1983)I/238 : Yale Trigonometric Parallaxes, Fourth Edition (van Altena+ 1995)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/337 : Gaia DR1 (Gaia Collaboration, 2016)J/AJ/103/638 : USNO Photographic Parallaxes.
