Detailed Description

A base class for absorption correction algorithms.

Common Properties:

InputWorkspace - The name of the input workspace.
OutputWorkspace - The name of the output workspace. Can be the same as the input one.
AttenuationXSection - The attenuation cross-section for the sample material in barns.
ScatteringXSection - The scattering cross-section for the sample material in barns.
SampleNumberDensity - The number density of the sample in Angstrom^-3.
NumberOfWavelengthPoints - The number of wavelength points for which numerical integral is calculated (default: all points).
ExpMethod - The method to calculate exponential function (Normal of Fast approximation).

This class, which must be overridden to provide the specific sample geometry and integration elements, uses a numerical integration method to calculate attenuation factors resulting from absorption and single scattering in a sample. Factors are calculated for each spectrum (i.e. detector position) and wavelength point, as defined by the input workspace. Path lengths through the sample are then calculated for the centre-point of each element and a numerical integration is carried out using these path lengths over the volume elements.

This algorithm assumes that the beam comes along the Z axis, that Y is up and that the sample is at the origin.
