Abstract:
More than 600 high resolution spectra of stars with spectral type F
and later were obtained in order to search for signatures of
differential rotation in line profiles. In 147 stars the rotation law
could be measured, with 28 of them found to be differentially
rotating.
Description:
Table B1 contains projected rotation velocities, measured ratios of
the first and second zeros of the broadening profiles Fourier
transform, latitudinal shear, effective temperature, absolute
magnitude and projected rotation period as calculated from the
projected rotation velocity and the radius for the field stars of
the sample.
Table B2 contains the same information for the stars observed in
clusters.
