Scaling relation parameters for both calibration samples.
| X-ray sample | Chandra | XMM-Newton |
|---|---|---|
| Y* | −0.29 ± 0.01 | −0.19 ± 0.02 |
| α | 1.70 ± 0.1 | 1.79 ± 0.08 |
| (1 − b) | 0.89 ± 0.04 | 0.78 ± 0.04 |
| Scatter | 21% | 18% |
Notes. In the case of the XMM-Newton sample, only the bias was reestimated in this work, as a full re-calibration of the scaling relation did not yield different results to Planck Collaboration XX (2014).
