The best-solution leads to an over-contact configuration of W-subclass of W UMa systems with a fill-out factor of 28%. Absolute parameters based on simultaneous solution of light and radial velocity curves are presented.eninfo:eu-repo/semantics/closedAccessbinaries : eclipsingbinaries : closestars : individual (EF Bootis)Article325433233510.1002/asna.200310174Q3WOS:0002215473000072-s2.0-4644337099Q3
