Spectral Energy Distributions (SEDs)

Spectral energy distributions (SEDs) show the amount of energy emitted by an object as a function of wavelength. SEDs are not the same thing as blackbodies! But stars can be approximated by blackbodies, so blackbodies come up a lot in the context of SEDs. This page covers concepts; there is another page on how to make SEDs.
