AN IMPORTANT NOTE: The current Quiz 7 (mismarked as Quiz 6 in some handouts) is about drawing an H-R diagram. The scale of absolute magnitudes SHOULD go from +20 at the bottom to -5 at the top, because we want the most luminous stars at the top. (The scale says +5 to -20, which makes no sense. I really wish someone who had noticed this had sent me an e-mail alerting me to the error!)
