bexriv: reflected e-folded broken power law, ionized medium

Broken power-law spectrum multiplied by exponential high-energy cutoff, , and reflected from ionized material. See Magdziarz & Zdziarski 1995, MNRAS, 273, 837 for details. Ionization and opacities of the reflecting medium is computed as in the procedure absori. The output spectrum is the sum of an e-folded broken power law and the reflection component. The reflection component alone can be obtained for . Then the actual reflection normalization is . Note that you need to change then the limits of  excluding zero (as then the direct component appears). If , there is no cutoff in the power law. The metal and iron abundances are variable with respect to those set by a command abund. Send questions or comments to aaz@camk.edu.pl .
