摘要

We present trigonometric parallaxes of 64 stellar systems with proper motions between 0'.5 yr(exp -1)and 1'.0 yr(exp -1) from the ongoing Research Consortium On Nearby Stars parallax program at the Cerro Tololo Inter- American Observatory. All of the systems are south of decl. = +30, and 58 had no previous trigonometric parallaxes. In addition to parallaxes for the systems, we present proper motions, Johnson-Kron-Cousins VRI photometry, variability measurements, and spectral types. Nine of the systems are multiple; we present results for their components, three of which are new astrometric detections. Of the 64 systems, 56 are within 25 pc of the Sun and 52 of those are in the southern hemisphere, comprising 5.7% of the total number of known southern 25 pc systems.
