Table 3:

Fit results in the search for the 6th harmonic using the cut-off power law model for the continuum above 13 keV. $\Delta \chi ^2$ is referred to the introduction of the further Gaussian absorption line. $E_{\rm abs}$ is the centroid value, $E_{\rm B}$ is the value corresponding to three times the centroid energy of the second harmonic, and $N_{\rm abs}$ is the line normalization. The null hypothesis probability is obtained using the F-test.
Phase 0.33-0.40 0.40-0.46
$E_{\rm abs}$ [keV] $71\pm3 $ $68.6\pm2.6$
$E_{\rm B}$ [keV] $66.9\pm0.3$ $70.74\pm0.15$
$N_{\rm abs}$ [keV] $4.5\pm2.5$ 3.1-0.6+1.3
$\Delta\chi^2{\rm (d.o.f.)}$ $221(168)\rightarrow215(166)$ $158(142)\rightarrow152(140)$
Null hypothesis probability 10% 5%
