Biases on cosmological parameters due to redshift uncertainties.

Case	ΔΩ_m/σ_{Ω_m}	Δσ₈/σ_σ₈	Δw₀/σ_w₀	Δw_a/σ_{w_a}
Realistic and QC yes	0.27 ± 0.16	0.11 ± 0.06	0.46 ± 0.26	0.24 ± 0.14
Realistic and QC no	0.28 ± 0.15	0.11 ± 0.06	0.46 ± 0.26	0.24 ± 0.13
Best and QC yes	0.09 ± 0.02	0.04 ± 0.01	0.16 ± 0.04	0.08 ± 0.02
Best and QC no	0.08 ± 0.02	0.03 ± 0.01	0.14 ± 0.04	0.07 ± 0.02

Notes. All values are given in units of σ considering the four different cases of redshift calibration (refer to Sect. 4.4 and Appendix C). The errors are given as standard deviations of the distribution displayed in Fig. 8. Note that they are given as symmetric only for reference.
