...but the gravitational field is supposed to be radial, not directed toward the accretion disk. IOW the polar directions are not "vertical", and angle should have no bearing. (The word vertical implies parallel with the direction of maximum gradient in the gravitational field). Regards, Robin van Spaandonk <[EMAIL PROTECTED]>
