We perform a detailed analysis of Cepheids in NGC 4258, the Magellanic Clouds, and Milky Way in order to verify the reliability of the theoretical scenario based on a large set of nonlinear convective pulsation models. We derive Wesenheit functions from the synthetic -->BVI magnitudes of the pulsators, and we show that the sign and the extent of the metallicity effect on the predicted period-Wesenheit ( -->P − W) relations change according to the adopted passbands. These -->P − W relations are… Expand
