Notes. Different τ error amplitudes (given by σϵ) and two cluster (sub-)samples are considered here. The percent levels correspond to the fractional changes found in the kSZ monopole error bar (third column), the 95% confidence limit for the kSZ-induced rms-excess (fourth column), and the kSZ dipole error bar (fifth column).
