TL;DR
This paper provides precise coordinates and 2MASS cross-identifications for nearly all stars in major nearby star catalogs, improving data accuracy and completeness for astronomical research.
Contribution
It offers a comprehensive update of star positions and cross-identifications, including proper motions, for the Gliese catalog and related nearby star lists.
Findings
Nearly all catalog stars have updated coordinates and cross-IDs.
Most positions are based on Hipparcos and 2MASS data.
The catalog includes proper motions and epoch 2000 positions.
Abstract
We provide precise J2000, epoch 2000 coordinates and cross-identifications to sources in the 2MASS point source catalog for nearly all stars in the Gliese, Gliese and Jahreiss, and Woolley catalogs of nearby stars. The only Gliese objects where we were not successful are two Gliese sources that are actually QSOs, two proposed companions to brighter stars which we believe do not exist, four stars included in one of the catalogs but identified there as only optical companions, one probable plate flaw, and two stars which simply remain un-recovered. For the 4251 recovered stars, 2693 have coordinates based on Hipparcos positions, 1549 have coordinates based on 2MASS data, and 9 have positions from other astrometric sources. All positions have been calculated at epoch 2000 using proper motions from the literature, which are also given here.
