Comparison of EPIC-PN full energy band temperatures with those obtained with ACIS-I (blue squares) and ACIS-S (red triangles). The N_H is frozen to the radio value of the LAB survey. For a comparison of the resulting best-fit parameters see also Fig. B.5 and Table 2. The red and blue lines show the powerlaw best-fit function (Eq. (3)) to the ACIS-S and ACIS-I subsamples, respectively.
