Same as Fig. 2, but the expected ICM fluxes are derived by fitting NH. Soft excess fluxes in some regions of A3571 remain nonetheless unexplained. In order to eliminate such excesses, we estimate that an NH of ﹩4.05^{+0.15}_{-0.2}\times 10^{20}﹩ (4﹩\arcmin﹩–8﹩\arcmin﹩ region) and ﹩3^{+0.5}_{-0.4}\times 10^{20}﹩ (12﹩\arcmin﹩–16﹩\arcmin﹩ region) would be required, significantly lower than the measured values (see Table 1).
