This model calculates the transmission of the interstellar medium using the
description of the ISM absorption of Rumph, Bowyer, & Vennes 1994, AJ 107,
2108. It includes neutral He autoionization features.
Between 1.2398 and 43.655 Angstroms (i.e. in the 0.28-10 keV range) the model also
accounts for metals as described in Morrison & MacCammon 1983, ApJ 270,
119.
The code uses the best available photoionization cross-sections to date
from the atomic data literature and combines them in an arbitrary mixture of
the three ionic species: HI, HeI, and HeII.
The model assumes that the data are expressed in Angstroms.
