A new ephemeris and fundamental parameters for the eclipsing binary star GSC 03612-1565 = V2647 Cyg.

Abstract (from CDS):

High precision light curves were obtained for the GSC 03612-1565 = V2647 Cyg eclipsing binary system in 2009 and in 2018. The solution for these curves allowed to estimate the limb darkening coefficients and spectral classes of components (F5V–F8V). Also a new ephemeris was computed, it is very different in comparison to a previous study by Otero et al. (2006). The circular orbit instead the elliptical was found.
