eplogpar:  log-parabolic blazar model with nFn normalization

eplogpar is a power-law with an index which varies with energy as a log parabola.

 

par1 = Ep	The peak energy in nFn
par2 = b	Curvature term
norm= K	The flux in nFn units at energy Ep keV

 

See for instance Tramacere et al., 2007 and Tramacere et al., 2009.
