The Henry Draper Catalog with Gaia IDs

This is the Henry Draper catalog (HD, Cannon & Pickering 1918-1924) as distributed by the Astronomical Data Center in 1989 (Vizier III/135A), with Gaia DR2 source_ids and positions added. The link to modern Gaia DR2 was done through Fabricius et al's match between HD and Tycho 2 (Vizier IV/25), TGAS to match Tycho 2 and Gaia DR1, and Gaia DR2 to match against Gaia DR1.
