Abstract:
The Case-Hamburg OB-star surveys (Luminous Stars in the Milky Way,
Catalogs III/76 and III/43) have been extended to galactic latitude
b=±30 for l=±60 using the Curtis Schmidt telescope and 4°
objective prism at the Cerro Tololo Inter-American Observatory. A
catalog of 234 OB stars and other objects with peculiar spectra is
presented along.
The positions were revisited by B. Skiff in May 2002, using the
finding charts; additional notes and cross-identifications have been
added in the course of this examination (see the "notes.dat" file).

Note (1): the origin of the position is abbreviated as follows:
B = Bordeaux meridian circle (2001A&A...376..325R 2001A&A...376..325R, Cat. I/272)
G = GSC-ACT (Cat. I/255)
T = Tycho-2 (2000A&A...357..367H 2000A&A...357..367H, Cat. I/259)
U = UCAC1 (2000AJ....120.2131Z 2000AJ....120.2131Z, Cat. I/268)
Note (2):
OB+, OB and OB- types indicate blue stars in increasing Balmer
absorption line strength -- most of them are blue horizontal branch
stars or O/B subdwarfs. 'MD' indicate metal deficient stars, 'e'
indicates emission in Balmer lines (Ce = Carbon star with emission, Ge
= G0 star with emission). WD are DA white dwarfs.
