Similar to Fig. 5 but for a smoothing scale of R_θ = 2.1 arcmin. For R_θ = 2.1 arcmin, and with galaxy selections consistent with DES-Y1 both across the full redshift range and within each of the four redshift bins of width 0.1, no significant bias is observed. The biases of the kSZ signal and velocities are consistent with unity within 1σ, and the biases of optical depth are within 1.34σ.
