Detailed Description

A set of SpectralElements.

Intended use:

Public interface

Review Status

Date Reviewed:

yyyy/mm/dd

Test programs:

tSpectralFit

Prerequisite

• SpectralElement class

Etymology

From spectral line and element list

Synopsis

The SpectralList class is a container for a set of spectral elements.

The list can be used in the SpectralFit class and in the SpectralEstimate class.

Example

Motivation

To have a container for fitting of spectral profiles to an observed spectrum

To Do

• add more profile types
