Parametric star formation history for a galaxy with a rotational velocity of 220 km s^-1 (black dashed line), 290 km s^-1 (green solid line), and 150 km s^-1 (blue solid line). The black dashed line shows the delayed star formation history given in Eq. (1), the red solid line the smoothly declining history (Eq. (A.1)) for a galaxy with a rotational velocity of 220 km s^-1. This figure can be compared to Fig. 2.
