The passage around this formula

…spectrum is only approximate even before synchrotron backgrounds are considered. What the storage-ring case does supply, honestly, is a parameter range: it is the one setting where the acceleration scale entering TUT_U is large enough for an Unruh-like correction to be even nominally comparable to measured precision, and the percent-level agreement between observed and standard-model-predicted polarization bounds any anomalous, acceleration-induced departure from ordinary detector response at that same…
