Abstract
Recently, it was suggested that the map-making procedure, which is applied to the time-ordered cosmic microwave background data by the WMAP team, might be flawed by hot pixels. This could lead to a bias in the pixels having an angular distance of about 141° from hot pixels due to the differential measuring process of the satellite WMAP. Here, the bias is confirmed, and the temperature two-point correlation function C(ϑ) is reevaluated by excluding the affected pixels. It is shown that the most significant effect occurs in C(ϑ) at the largest angles near ϑ = 180°. Furthermore, the corrected correlation function C(ϑ) is applied to the cubic topology of the Universe, and it is found that such a multi-connected universe matches the temperature correlation better than the ΛCDM concordance model, provided the cubic length scale is close to L = 4 measured in units of the Hubble length.
