Figure 15: Expected constraints on the growth rates in each redshift bin. For each the central
error bars refer to the Reference case while those referring to the Optimistic and Pessimistic case
have been shifted by and respectively. The growth rates for different models are
also plotted: CDM (green tight shortdashed curve), flat DGP (red longdashed curve) and a model
with coupling between dark energy and dark matter (purple, dot-dashed curve). Here we plot again
the model by [456] with (blue shortdashed curve) together with the model by [864]
(cyan solid curve) and the one by [904] (black dotted curve). Also in this case it will be possible to
distinguish these models with next generation data.
