| 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. |
