Description:
Magnitudes in V and B-V and U-B colors observed by the 91-cm telescope
at Okayama are presented for 109 stars including both classical and
marginal barium stars. The two-color diagram shows a fair amount of
spread. This can be interpreted by interstellar reddening and variable
amounts of line blocking effect. Both classical and marginal barium
stars form a fairly homogeneous group.
