Notes.

(a)

Flux of the O VII line, fitted with a Gaussian profile. Units are ×10−4 photons cm−2 s−1.

(b)

Equivalent width of line in units of eV.

(c)

Improvement in χ2 upon adding the O VII line component.

(d)

Flux of the Fe K line, fitted with a Gaussian profile. Units are ×10−5 photons cm−2 s−1.

(e)

Continuum flux from 0.3–2.0 keV or 2–10 keV in units ×10−11 ergs cm−2 s−1.
