xsect

set the photoionization cross-sections

Change the photoelectric absorption cross-sections in use.

Syntax: xsect [bcmc|obcm|vern]

The three options are: bcmc, from Balucinska-Church & McCammon (1992) with a new He cross-section based on Yan et al. (1998); obcm, as bcmc but with the old He cross-section, and, vern, from Verner & Yakovlev (1995) and Verner et al. (1996). This changes the cross-sections in use for all absorption models with the exception of wabs, the tbabs family of models, amd ismabs.
