Abstract:
We present results from light curve fits to the photometry of 13
chromospherically active stars, covering the time evolution of the
rotational phase of their primary light curve minimum and the light
curve amplitude.
Description:
The data table contains estimates of the light curve minimum phases
and amplitudes retrieved by the continuous period search analysis
(Lehtinen et al., 2011A&A...527A.136L 2011A&A...527A.136L, Cat. J/A+A/527/A136). The
results for different stars have been labeled according to the names
of the stars.
