We determine the variation with radius of the physical parameters (scale height, central density, and central temperature) of a stationary self-gravitating, magnetized accretion disk at radii larger than 102RG. Our results are relevant in the context of line and continuum emission from the outer region of the disk. We have also studied the influence of self-gravitation and magnetic fields over typical radii, and have shown that the value of RBB is larger than that computed by Collin- Souffrin & Dumont by a factor of about 4.7.
