Description:
This catalog is an improved version of the Blanco et al. compilation,
with additional data from the Catalog of Stellar Identifications. and
additional stars apparently missed from the publications surveyed by
Blanco et al. (see Ochsenbein 1974A&AS...15..215O 1974A&AS...15..215O, section 9)

--------------------------------------------------------------------------------
Note (1): the multiplicity code is:
21,22 = one HD star overlaps several stars
99 = one star overlaps 2 consecutive HD numbers
00 = otherwise
Note (2): the Durchmusterung code is:
00 = star from Bonner Duchmusterung (BD, Cat. I/119, I/122)
01,02 = component of a BD star
20 = star from Cordoba Duchmusterung (CD, Cat. I/114)
21,22 = component of a CD star
40 = star from Cape Photographic Duchmusterung (CPD, Cat. I/108)
41,42 = component of a CPD star
Note (3): Numbers below 21000 (range 1-20705) correspond to the stars
existing in the printed version of the catalog; numbers >21000 were
assigned to stars missing in the Blanco's publication.
