diskm

A disk model with gas pressure viscosity. The spectrum from an accretion disk where the viscosity scales as the gas pressure. From Stella and Rosner 1984, ApJ, 277, 312.

par1	 = 	accretion rate in Eddington luminosities

par2	 = 	central mass in units of solar mass

par3	 = 	inner disk radius in gravitational ( = 3 Schwarzschild) radii

par4	 = 	viscosity

K  	 = 	cos(i)/d , where i is the inclination of the disk

       		and d is the distance in units of 10 kpc
