Description:
A finding list is presented for OB stars in a 75 square degree region
centered on η Carinae, observed with the the 50/65/175cm Schmidt
telescope of the Uppsala Southern Station at Mount Stromlo, with an
objective prism giving a dispersion of 470Angstrom/mm et Hγ.
Completeness between 8.5 and 11.5 was the goal.
Accurate positions were added by Brian Skiff (Lowell Observatory) on
2003-Aug-18 for non-HD/CPD stars, and on 2009-12-29 for all stars; the
result is the file "positions.dat". Coordinates were found with VizieR
usually from UCAC2 or Tycho-2. V magnitudes were added from published
photoelectric data, ASAS-3, or Tycho-2. In the remarks the CD names
were added if available for CPD stars.
The implicit spectral type is 'OB', but some follow-up observations
from other sources, notably by Graham himself (1970AJ.....75..703G 1970AJ.....75..703G)
show that some of the stars are of later type.

History:
* The catalogue was originally prepared by G. Lynga and forwarded to CDS
in 1972 (see 1972BICDS...3....2J 1972BICDS...3....2J)
* 06-Sep-1996: a short description was added at ADC by Nancy Grace Roman
* 29-Dec-2009: accurate positions added by Brian Skiff (Lowell Obs.)
* 06-Feb-2016: documentation completed at CDS, and "Ton" designations added.
