Improved astrometry bor BE74 stars
Listed in IVOA Registry (Virtual Observatory)
Accurate astrometry is required to reliably cross-match 20th-century catalogues against 21st-century surveys.
Description
The present work aims to provide such astrometry for the 625 entries of the Bohannan & Epps (BE74; 1974A&AS...18...47B) catalogue of H{alpha} emission-line stars. BE74 targets have been individually identified in digital images and, in most cases, unambiguously matched to entries in the UCAC4 (I/322) astrometric catalogue.
