Scientific paper

Radial velocities of the primary components of the two RS CVn-type binary systems SV Cam and XY UMa are presented, for the first time for XY UMa. Neither secondary component could be detected. A change of 5.0 + or - 13 km/sec in the systemic velocity of SV Cam is found over 40 years, which lends some support to the current model of SV Cam being a triple system. If the masses of the G3 V primary components of both systems are assumed to be 1 solar mass, then the secondaries are 0.7 (SV Cam) and 0.6 (XY UMa) solar masses; all four stars are main sequence objects with SV Cam being rather more evolved than XY UMa.
