New, updated, and/or revised CCD parallaxes determined with the StrandAstrometric Reflector at the Naval Observatory Flagstaff Station (NOFS) arepresented. Included are results for 309 late-type dwarf and subdwarf starsobserved over the 30+ years that the program operated. For 124 of the stars,parallax determinations from other investigators have already appeared in theliterature and we compare the different results. Also included here is new orupdated $VI$ photometry on the Johnson-Kron-Cousins system for all but a few ofthe faintest targets. Together with 2MASS $JHK_s$ near-infrared photometry, asample of absolute magnitude versus color and color versus color diagrams areconstructed. Since large proper motion was a prime criterion for targeting thestars, the majority turn out to be either M-type subdwarfs or late M-typedwarfs. The sample also includes 50 dwarf or subdwarf L-type stars, and four Tdwarfs. Possible halo subdwarfs are identified in the sample based ontangential velocity, subluminosity, and spectral type. Residuals from thesolutions for parallax and proper motion for several stars show evidence ofastrometric perturbations.
