This is an X-ray spectral model that describes the reprocessing of X-rays in a torus-shaped medium. This e-torus model is based on Ikeda et al. 2009. The intrinsic spectrum of the AGN is described by a power law with an high-energy exponential cut-off. This model was used in Ikeda et al. (2009), Awaki et al. (2009).
There are two table model files available: e-torus_20161121_2500M.fits and e-torus_hc_20161121_2500M.fits These files were updated on 11/28/16 to give the correct result when calculating the model on energies beyond those tabulated in the original files.
A brief explanation of the model and illustrations of its use are contained in torus_model_v02a.pdf.
The table model has five parameters in e-torus_20161121_2500M.fits:
The table model has five parameters in e-torus_hc_20161121_2500M.fits:
These are multiplicative table models and the PhoIn or E_Cut parameters must be linked to those in the cut-off power-law model to which the multiplicative model is applied.
