UVOIR bolometric luminosity vs. time since bolometric peak. Our.Ia models are shown as thick lines as labeled; thick solid lines show the less massive envelopes for each core mass, thick dashed lines show the more massive envelopes, and black, red, and blue lines denote 0.6, 1.0, and 1.2  M _☉ cores, respectively. Thin black lines are UVOIR bolometric light curves from integrated and blackbody fits for observed SNe as labeled.
