Summary of the impact of the considered uncertainties on the measurement M_CMBlens/M_SZ.

Uncertainty	$\frac{M_{CMBlens}}{M_{SZ}}$ ${{{M_{{\rm{CMBlens}}}}} \over {{M_{{\rm{SZ}}}}}}$
Dispersion due to kSZ	±0.015
Profile up to 3 × r₅₀₀	+0.017
Profile up to 7 × r₅₀₀	−0.019
Miscentring	−0.008
Error on z	±0.001
Error on M₅₀₀	±0.007

Total	±0.026

Bias due to kSZ	−0.060
No relativistic SZ	− 0.012

Notes. The major uncertainty is the profile modelling (about 10% of the statistical error). The other uncertainties are of order of 1%. The considered uncertainties and their modelling are described in dedicated subsections in Sect. 6.
