Notes. Upper panel: parameters that are fixed for each simulation. Middle panel: distributions of Monte Carlo parameters that are drawn randomly. Lower panel: quantities that are derived from or controlled by other parameters. The upper and lower limits denote 84th and 16th percentiles, respectively.
