UVBY photometry of wide visual double stars. III
The observed magnitudes and color indices b-y, m1, and c1 are obtainedfor the components of 31 visual double stars and one triple system. Theabsolute magnitudes of the components are calculated, and the physicalcharacteristics of the systems are examined.
| UVBY observations of A, F, G and K field stars
Photoelectric data in the uvby system have been obtained for about 800southern stars of the Hipparcos Input Catalog (Grenon, 1982, 1985). Mostof the stars are F and G main sequence and fall in the magnitude range V= 8-11.
