2192 II/192 UBV Photometry of Barium Stars E Watanabe M Yutani Y Yamashita Publ. Nat. Astron. Obs. Japan 3 1 1993 1993PNAOJ...3....1W V/81 : Taxonomy of Barium Stars (Lu 1991) Photometry, UBV Stars, barium Stars, late-type 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.
