Results for the XSPEC spectral model fits.
| Parameter | XMM2 (pn) | CXO1 (ACIS) | CXO1 unbina |
| NH/ 1022 cm-2 | 0.08(...,0.72) | 13.8(4.4,55.9) | 20.5(3.3,55.2) |
| kT [keV] | 8.4(1.3,...) | 4.1(0.55,...) | 2.3(0.55,...) |
| norm/ 10-5 cm-3 | 0.9(0.4,2.3) | 7.3(1.6,1840) | 20.4(1.6,1900) |
| LX,best [erg s-1] | 4.3 × 1029 | 3.5 × 1030 | 7.8 × 1030 |
| Statistic/d.o.f. | 0.04/1 | 0.04/1 | 17.9/17 |
Notes. Norm = EM/(4π1014d2), where d = distance to the star (520 pc) and LX,best is the unabsorbed LX for the best fit. Statistic/dof is χ2 for Cols. 2 and 3, and C for Col. 4, divided by the number of degrees of freedom; 90% confidence ranges (for one parameter of interest) are given in parentheses. Ellipsis dots indicate an unconstrained error range.
