dust

A modification of a spectrum due to scattering off dust on the line-of-sight. The model assumes that the scattered flux goes into a uniform disk whose size has a 1/E dependence and whose total flux has a 1/E tex2html_wrap_inline12909 dependence.

par1	 = 	scattering fraction at 1 keV

par2 = size of halo at 1 keV in units of the detector beamsize
