This is a reimplementation of the Emission Spectra Javascript simulation by Andrew Duffy, from his collection at https://physics.bu.edu/~duffy/sims.html

It includes the addition of multiple line display and absorption spectra.

This simulator is part of the Foothill AstroSims project, which is aiming to reimplement, in HTML5, Flash-based simulations that are used in Foothill Astronomy courses, as well as developing new simulations covering topics previously unaddressed by Astro-education simulations.
