Abstract

By using the same algorithm in the Baade–Wesselink analyses of Galactic RR Lyrae and Cepheid variables, it is shown that, within 0.03-mag 1σ statistical error, they yield the same distance modulus for the Large Magellanic Cloud. By fixing the zero-point of the colour–temperature calibration to those of the current infrared flux methods and using updated period–luminosity–colour relations, we get an average value of 18.55 for the true distance modulus of the LMC.
