       "cross_section"
	   Example:

	      $xsec = Xray::Absorption -> cross_section($elem, $energy, $mode);

	      @xsec = Xray::Absorption -> cross_section($elem, @energy, $mode);

	   The $mode argument is different here than for the other resources.  The options are "xsec", "photo", "coherent" and "incoherent",
	   telling this method to return the full cross-section or just the photoelectric, coherent, or incoherent portions.

	   The values for all cross-sections are computed as log-log polynomials as described in the original paper by Shaltout et al.

NAME
       Xray::Absorption::Shaltout - Perl interface to the Shaltout tables

SYNOPSIS
	  use Xray::Absorption;
	  Xray::Absorption -> load("shaltout");

       See the documentation for Xray::Absorption for details.

DESCRIPTION
       This module is inherited by the Xray::Absorption module and provides access to the data contained in

	 Update of photoelectric absorption coefficients in the tables of McMaster
	 Abdallah Shaltout, Horst Ebel, and Robert Svagera
	 X-Ray Spectrometry(2006) vol. 35, p. 52-56

       The data is contained in a database file called shaltout.db which is generated at install time from a flat text database of the data which
       can be found at <http://www.ifp.tuwien.ac.at/forschung/abdallah.shaltout/> as explained in the reference.

       The required Chemistry::Elements module is available from CPAN in the miscellaneous modules section.

EDGE AND LINE ENERGIES
       The Shaltout data resource includes all K, L, M, and N edges but does not provide any of the line energies.  An minimal set of line
       energies is imported from the McMaster data resource.

BUGS AND THINGS TO DO
       This module has not be tested sufficiently.
