Quick Reference

A measure of the strength of a line in a spectrum. An emission line is an increase in the intensity of a spectrum, while an absorption line is a dip. The equivalent width is the width of the spectral continuum that has the same area as the line. Values are negative for emission lines, positive for absorption lines.
