Table 1: Short-term X-ray variability of NGC 6251.
Energy band $\langle r\rangle$ $\chi^2_{\rm red}$ $P_{\chi^2}$ $F_{\rm var}$ a
(keV) ( ${\rm s^{-1}}$) (14 d.o.f.) (%) (%)
0.4-0.7 keV 0.49 0.54 89.6 -
0.8-1 keV 0.34 1.40 14.8 $2.2\pm1.4$
1.2-1.5 keV 0.36 1.48 11.7 $2.1\pm1.3$
1.8-3 keV 0.41 1.59 8.1 $2.3\pm1.2$
3-10 keV 0.39 1.66 6.2 $2.8\pm1.3$
a The errors on $F_{\rm var}$ are calculated as in Edelson et al. (2002) and should
be considered conservative estimates of the true uncertainty.
