Abstract
We show that only 12 out of 27 analyzed binaries have data good enough for reliable determination of i(orb) and i(rot). In 4 systems (out of these 12) assumption about coplanarity of rotational equatorial plane and orbital plane is justified. In the remaining cases rotational axe s are not perpendicular to the orbital planes (non-coplanar case). The commonly accepted assumption about the coplanarity of rotational and orbital planes should be revised.
