Scientific paper

The Baade-Wesselink inversion technique was applied to three pulsators:
the RR(ab) stars SW Dra and X Ari, and the classical Cepheid, U Sgr. A
surface brightness parameterization using the V-K color was found to be
superior for RR Lyrae stars, while B-V is superior for classical
Cepheids. A consistent radius was obtained for SW Dra but not for X Ari.
