Scientific paper

The recently developed CORS method (Caccin et al., 1981) is applied to the photometric data of Walraven et al. (1964) to determine improved radii for the three classical Cepheids V381 Cen, V500 Sco, and SV Vel. The CORS method is described, and radius curves for the Cepheids are presented. The obtained radii are in good agreement with theoretical computations for the center of the instability strip (Cogan, 1978). From an analysis of the photometric data, some parameters are computed and shown.
