Multi-band UV and optical light curves for the weak-wind model r1w1 (left), the strong wind model r1w5r (center), and the model with an extended scale height r1w1h (right). The time origin corresponds to shock breakout (taken to be when the luminosity at the photosphere rises to 10⁴² erg s^-1). Models r1w5r and r1w1h both show much shorter rise times in most/all bands than the weak-wind model r1w1.
