Twenty-four 10 A/mm spectra of the W UMa binary AH Vir have been analyzed for radial velocities and for geometrical parameters of the system components by the method of spectral-line broadening functions. It is shown that the broadening functions determined through the linear restoration process are much better defined than cross-correlation functions, even in the presence of broad spectral features. A new spectroscopic orbit for AH Vir has been determined on the basis of radial velocity information contained in the broadening functions. A combination of this orbit with a parallel solution for the geometric elements gave a new set of absolute elements of the system: a=2.80R ○ ., M 1 =1.36M ○ ., M 2 =0.41 M ○ ., R 1 =1.40R ○ ., and R 2 =0.83R ○ .
