Fig. 4

Left: evolution of the ionization fraction for several functions, all having the same optical depth, τ = 0.06: green and blue are for redshift-symmetric instantaneous (δz = 0.05) and extended reionization (δz = 0.7), respectively; red is an example of a redshift-asymmetric parameterization; and light blue and magenta are examples of an ionization fraction defined in redshift bins, with two bins inverted between these two examples. Right: corresponding EE power spectra with cosmic variance in grey. All models have the same optical depth τ = 0.06 and are essentially indistinguishable at the reionization bump scale.

This figure is made of several images, please see below:
