Be stars in open clusters. III. A uvby-beta calibration for the astrophysical parameters of Be stars
Abstract
We present an empirical calibration of the uvby-beta photometric system to determine the intrinsic colours and indices and the astrophysical parameters of the underlying star, valid for Be stars earlier than B5. The procedure allows the determination of the interstellar reddening with an accuracy of 0.033 mag. (rms), and the absolute magnitude with an accuracy of 0.7 mag.
