Detailed Description

Definition of matter parameters necessary for HEED. This is photoabsorption cross section, dielectric constant and other parameters related to these. All the parameters depending on energy are kept in arrays associated with specific energy mesh, which should be defined.

The principle is ordinary: definition of just a class. To the contrary with wcpplib/matter, there is no any global "database" and no formal ban to duplicate these definitions (although there would not be sense in duplication).

Constructor & Destructor Documentation

◆ HeedMatterDef() [1/3]

Heed::HeedMatterDef::HeedMatterDef ( )

default

Default constructor.

Referenced by copy().

◆ HeedMatterDef() [2/3]

		MatterDef *	amatter,
		const std::vector< AtomPhotoAbsCS * > &	faapacs,
		double	fW = 0.0,

Constructor. If fW == 0.0, the program takes mean W from molecules for gas or from atoms for matters. If fF is input as 0.0, it is assigned to be mean for gas. For matters this is the terminating error.
