dc.description.abstract Light curve analysis of contact binaries are presented and compared with previous cross-correlations velocity data. The critical parameter q (mass-ratio) obtained by a grid technique is confronted with its spectroscopic value. For total eclipsing systems, the agreement of both values is always reasonable including the cases of shallow light curves. For spatial eclipses systems, convergent photometric and spectroscopic results are obtained for an important set of stars. Two exceptions are V523 Cas and V508 oph for which some explanations are intended. From the present study it is concluded that reliable data can be obtained from pure photometric solutions by means of grid techniques. en
