What the article says around this equation

Where DdetD_{\rm det} is well defined, it can be evaluated, and the cleanest case where it is well defined and non-trivial is a comparison between two accelerated trajectories, both with finite normalizable spectra, differing only slightly in acceleration. This is the one calculation in this article carried to an explicit number, and it is carried out by hand, exactly, as a leading-order (linear-response) expansion — not a simulation, and not a claim about any measured system.
