Marginalised 1σ errors on cosmological parameters, relative to their corresponding fiducial values for a flat (upper panels) and non-flat (lower panels) spatial geometry, in (w0, wa, γ) cosmology. Left (right) panels: pessimistic (optimistic) settings, as described in the text. The histogram refers to different observational probes: GCs (purple), WL (blue), GCs+WL (orange); none of the available codes allow us to include GCph or cross-correlation, while also allowing γ to vary. For wa we show the absolute error, since a relative error is not possible for a fiducial value of 0.
