Our data consist of differential light curves collected in the filters B and V which have been analysed using the method of Wilson-Devinney (Phoebe). After identification of an adequate binary model and removal of the best-matching light curve solution, we performed a Fourier analysis of the residual B and V light curves to investigate the pulsational behaviour. Description: Tables of differential magnitudes in the sense (CT Her - C1), used to define the B and V light curves, are given in both filters. The radial velocities were measured with the cross-correlation technique using synthetic spectra obtained with the programme SPECTRUM, and a grid of LTE-atmosphere models of solar-type chemical composition. Also tabulated are the cycle numbers and the O-C values corresponding to the linear resp. the parabolic model which best represent the evolution of the orbital period of this binary system.
