SFH generated with the sfh2exp, sfhdelayed, and sfhperiodic modules. These represent the cases of two decreasing exponentials (blue), a single decreasing exponential (orange), one increasing exponential (green), a delayed SFH with different timescales (red and purple), a periodic rectangular SFH (brown), a periodic exponential SFH (pink), and the rotation velocity-dependent SFH of Buat et al. (2008; grey). We point out the transitory phase for the periodic exponential as each of the decaying exponentials combine. The exact parameters are indicated in the box. All SFHs have been normalised to have formed 1 M_⊙ over 13 Gyr. The diversity of generated SFHs allows for an important flexibility in the modelling.
