UVW2, B, and R band light curves obtained with cmfgen for models r1w1, r1w1h, r1w4, r1w5h, r1w5r, r1w6, and r2w1. The time origin corresponds to shock breakout (taken to be when the luminosity at the photosphere rises to 10⁴² erg s^-1). The variations in atmosphere/wind density have considerable impact on the early-time light curves, generally reducing the rise times and potentially introducing breaks in the light curves (e.g., model r1w6).
