The beam pattern of soft X-ray emission generated in a 'polar cap' at the surface of a white dwarf is calculated with allowance for absorption in a cylindrically symmetric accretion column uniform with respect to height. An algorithm which can be used to determine the orientation of the magnetic axis of the compact star from the orbital curve of the soft X-ray flux is presented. Values of the orbital inclination in the 51-64 deg range and of the angle between the axis of rotation and the magnetic axis in the 30-34 deg range are obtained for the polar AM Herculis for different model parameter values. It is found that the region of emission is located above the surface of the white dwarf while the absorbing matter is located higher in the accretion column.
