Scientific paper

Parallax data are given for 62 binary and proper motion stars based on observations obtained between May 1987 and March 1988. The data presented in tabular form include reference positions, identifiers (BD and GC numbers, if any), visual magnitudes, and spectral types. Mass ratio results for eight binary stars are also presented. Notes are provided which indicate the inclusion or replacement of previous measurements and which reductions have been applied.
