Radial-velocity measurements and sine-curve fits to the orbital velocityvariations are presented for the sixth set of ten close binary systems: SV Cam,EE Cet, KR Com, V410 Cyg, GM Dra, V972 Her, ET Leo, FS Leo, V2388 Oph, II UMa.All systems except FS Leo are double-lined spectroscopic binaries. The type ofFS Leo is unknown while SV Cam is a close, detached binary; all remainingsystems are contact binaries. Eight binaries (all except SV Cam and V401 Cyg)are the recent photometric discoveries of the Hipparcos satellite project. Fivesystems, EE Cet, KR Com, V401 Cyg, V2388 Oph, II UMa, are members ofvisual/spectroscopic triple systems. We were able to observe the close binarysystem EE Cet separately of its companion, but in the remaining four systems wecould separate the spectral components only through the use of thebroadening-function approach. Several of the studied systems are primecandidates for combined light and radial-velocity synthesis solutions.Comment: AASTeX5, 5 figures, 2 tables, modified after the AJ revie
