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.

The Durchmusterung identifier includes, in place 10, a component
identifier if there are two or more HD stars with the same DM number.
For multiple systems included in the Washington Catalog of Visual Double
Stars (WDS, Worley 1984) the same designations are given.
In place 11, there is a lower case letter identification for BD
supplemental stars (Warren and Kress 1980).
The following special values photovisual magnitude indicate unusual
object types:
===== ====================================
20.0 nebula (Neb in published catalog)
30.0 variable (var. in published catalog)
40.0 nova (Nov. in published catalog)
50.0 cluster (Cl. in published catalog)
NULL no value in published catalog
===== ====================================
The following codes are used in the remarks:
D
Entry deleted because it is a duplicate
or does not refer to a real star (see
Table 4)
E
Image is at edge of plate
G
Position and BD number taken directly
from AGK and precessed to 1900
M
Multiple images used. Only one intensity
is included (both are in the published
catalog, however)
R
There is a remark for this star in the
published catalog
\*
Spectral type refers to a cluster, nebula
or nebulous star. (Occurs in the Magellanic
Cloud fields only.)
