Abstract:
We present the second catalog of averaged quadratic effective magnetic
fields <Be> of 1212 main sequence and giant stars, and 11 white
dwarfs. Our sample includes a subset of 610 chemically peculiar
early-type stars. Some stars in the sample are members of several open
clusters. The catalog was derived from measurements of the
longitudinal magnetic field strength Be for stars, which were
scattered in the published sources.
Description:
Averaged longitudinal magnetic fields <Be> and other data are
listed. For each star we present HD number, spectral type, <Be>, rms
standard error of <Be>, chi2 for one degree of freedom, method of
Be determination, reference number and comments.
