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.
|par1||accretion rate in Eddington Luminosities|
|par2||central mass in solar mass units|
|par3||inner disk radius in gravitational (= 3 Schwarzschild radii)|
|norm||where is the inclination of the disk and is the distance in units of 10 kpc|
