Scientific paper

Trigonometric parallaxes determined at the U.S. Naval Observatory from plate material obtained with the 1.55-m astrometric reflector are listed. Included are parallax determinations for 89 single stars and for both components of four common-proper-motion binary systems. Of these, 94 are considered 'definitive' in the sense that they are based on sufficient plate material (generally, 40-50 plates per series) covering a sufficient time interval (average of 4.6 yr per series); thus further precision can be expected to accrue only as (approximately) the square root of the total number of plates employed in the solution.
