Statistical properties of the cross-calibration bias parameters.
| Pair | a0 | a1 | a2 | a3 | a4 |
|---|---|---|---|---|---|
| MOS1/pn | 0.93±0.12 | 0.25±0.19 | −0.15±0.09 | 0.03±0.01 | −0.002±0.001 |
| MOS2/pn | 0.91±0.10 | 0.30±0.13 | −0.19±0.08 | 0.04±0.01 | −0.003±0.001 |
Notes. The centroids and widths of the Gaussian fits to the distributions of the fourth-order polynomials we used to model the cross-calibration bias in the 0.5–6.1 keV band for each individual cluster. The uncertainties correspond to the 68% confidence level and contain both the statistical uncertainties and the effect of the scatter of unknown origin discussed in Sect. 5.3.
