Notes. Δχ2 = χ2Nd.o.f. is the difference from the mean assuming that the best-fit base ΛCDM model (fitted to Planck TT+lowP) is correct and Nd.o.f. is the number of degrees of freedom (set equal to the number of multipoles). The sixth column expresses Δχ2 in units of the expected dispersion, , and the last column lists the probability to exceed (PTE) the tabulated value of χ2.
