Scientific paper

The color excesses of eleven cepheids have been determined with the aid of photometry of field stars found in the proximity of the variables. A comparison of the color excesses with previous color-excess results is given. Four cepheids: RT Aur, DT Cyg, Zeta Gem, and T Vul, have relatively small and well-established reddening values. These four stars, along with Alpha UMi, can serve as standards to calibrate reddening-free indices with intrinsic color indices such as (b-y) or (B-V).
