Caption: Fig. 7.
Radius of the ionization front in units of the time‐varying Strömgren radius (see eq. [8]), for sources that turn on between redshifts z = 10 and z = 100 and have the photon production rate shown by the solid line in Fig. 4. The turn‐on redshifts of the 17 curves are equally spaced in log z.
