Spectral/Spectroscopy Discipline Namespace Outline

<sp:Spectral_Characteristics> is the public entry point to the Spectral Discipline namespace. This class contains all other Spectral classes and must be included to gain access to them. Below is a summary outline of all classes and attributes currently available in the Spectral Discipline dictionary, in the order in which they would appear in a label if every single one was used.

Note that there are no real cases in which every single discipline class and attribute would appear in a single label. The point of this outline is primarily to catalog what is present and show the required ordering within classes when they are included in a label.

Note: The abbreviated form “(Energy|Frequency|Wavelength|Wavenumber)” is used for those parallel classes that have identical structure but names that are tied to the requirements for units of measure. The form used must be consistent with the value of the sp:spectral_bin_type> attribute.
