Notes. The deviations are measured with respect to the estimates obtained from the combined M1+M2 profile with the Method 1 for the whole sample of 44 clusters. Dataset: (Method 2) Method 2 is used for mass reconstruction; (M2) only the T(r) profile from M2 is used; (T3D) the deprojected spectral measurements of T(r) are used in Method 1 instead of the projected estimates of Tmodel (see Sect. 3); (fit ngas) a model fitted to the gas density profile is used in Method 1; (Pout) the outer value of the pressure is not fixed.
