diskbb

The spectrum from an accretion disk consisting of multiple blackbody components. For example, see Mitsuda et al., PASJ, 36, 741, (1984), Makishima et al., ApJ 308, 635, (1986).

par1	 = 	temperature at inner disk radius (keV)

K	 = 	((Rin/km)/(D/10kpc))  , where Rin is the inner

 		disk radius, D the distance to the source, and    the

  		angle of the disk
