Same as Fig. 11, but now including Gaussian redshift errors with dispersion equal to the rms value measured for the VIPERS data, added to the mock galaxy redshifts. Here the dashed lines correspond to the use of a Lorentzian damping only, which in Fig. 11 was found to perform at best. With redshift errors, this needs to be supplemented by a further Gaussian damping factor, with dispersion fixed to the above rms error value, to yield the values described by the filled symbols.
