disk: accretion disk, black body

The spectrum from an accretion disk, where the opacities are dominated by free-free absorption, i.e., the so-called blackbody disk model. Not correct for a disk around a neutron star. 


accretion rate in Eddington Luminosities


central mass in solar mass units


inner disk radius in gravitational (= 3  Schwarzschild radii)


2cos(i)/d^2 where i is the inclination of the disk and d is the distance in units of 10 kpc
