Description
Based on dense series of photoelectric observations and on our radial-velocity measurements, the radii of 62 northern Cepheids are calculated by Balona's method. For each star there are five radius calculations. Two color indices, (B-V) and (V-R), were used as the effective temperature indicators. All light curves in V, B-V and V-R magnitudes together with the descending part light curves were used to exclude shock-wave influence. For calculations of radii of spectroscopic binaries (=sb) were used pulsational radial velocity curves.
