Cartoon picture (top) and examples (bottom) of our model SFH, displayed as the SFR as a functionof t_obs − t where t_obs is the time of observation (z ~ 3.7). In the top row, we show the parameters of the model SFH in black, and the post-processed quantities in red. The examples shown in the bottom row are a roughly constant SFH since the Big Bang (purple), a roughly constant SFH starting 1 Gyr ago (green), a roughly constant SFH with an abrupt quenching 300 Myr ago (blue), a brief and old burst (yellow), and a slowly rising SFH with a recent decline (red). Many more combinations are possible but not shown for clarity.
