Notes.

^(a)

Measured line energy in the NGC 7582 rest frame.

^(b)

Improvement in C-statistic upon adding the line.

^(c)

The parameters of the Fe Kα emission lines refers to the best-fit model after the inclusion of the possible Compton shoulder and the EW is against the total observed continuum.

^(f)

Denotes the parameter is fixed.

^(t)

Indicates that the σ is tied to the width of another transition from the same ion specie.
