X-ray cool-core estimators.
| Cool-core estimator | |
|
|
|
| Tcore − Tmax − Tavg | 4.6 − 8.0 − 5.7 [keV] |
| ZFe,c/Z⊙ |
|
| c SB | 0.150 ± 0.007 |
| t cool,c | 0.06 ± 0.01 [Gyr] |
| K c | 9.9 ± 2.0 [keV cm2] |
Notes. The quoted temperature and metallicity values correspond to the projected quantities, whereas the central cooling time and central entropy values are based on deprojected quantities.
