Its job in the formula

FxF_x is an input to the expression that computes the quantity on the left.

The passage around this formula

Fx(Ω)\mathcal F_x(\Omega) , viewed as a function of Ω\Omega for fixed everything else, has a natural reading as a spectrum: it says how much excitation probability accumulates at each possible gap, for a whole notional bank of detectors sharing one trajectory, one switching profile, and one field state, differing…
