Description:
We have refined the CORS method, introduced in 1980 for the
computation of the Cepheid radii, in order to extend its applicability
to recent and extensive sets of observations. The refinement is based
on the computation, from observational data only, of one of the terms
of the solving equation, previously based only on precise calibrations
of photometric colors. A limited number of assumptions, generally
accepted in the literature, is used. New radii are computed for about
70 Cepheids, and the resulting P-R relation is discussed.
