Spectral Line Energy Distribution

(function or plot of brightness of lines in a spectrum)

A Spectral Line Energy Distribution (SLED) is a Spectral Energy Distribution with an emphasis on Spectral Lines, i.e., to identify a gas and its Temperature by analysis of the lines and their implied molecular energy level. A presentation could be a bar graph displaying the relative energy from some astronomical object, of various lines in a Line Series, the set of lines such as the Balmer Series, associated with electron energy levels of some specific Element or compound.
