J 2000.0 positions and proper motions of 257 stars in the central part of the Praesepe astrometric standard region
Abstract
We given the J2000.0 position and proper motions of 257 stars in the central 1.5° × 1.5° area of the Praesepe astrometric standard region with accuracies of 0.005~0.10 arcsec for the position in each direction and 0.0002~0.006 arcsec/yr for the proper motions in each direction.
