get_xsxsect

Synopsis

Return the cross sections used by X-Spec models.

get_xsxsect()

Example

>>> get_xsxsect()
'bcmc'

PARAMETERS

This function has no parameters

Return value

The return value from this function is:

val -- The value of the photoelectric absorption setting: one of 'bcmc', 'obcm', and 'vern'.

XSPEC version

CIAO 4.16 comes with support for version 12.13.1e of the XSPEC models. This can be checked with the following:

% python -c 'from sherpa.astro import xspec;
print(xspec.get_xsversion())'
12.13.1e
