The passage around this formula

…where the projected area onto Earth’s equatorial plane is close to the full value. With Earth’s sidereal rotation rate Ω\Omega ≈\approx 7.292×\times10^{-5}\,rad s−1\mathrm{rad\,s^{-1}} [ 10 ] , the accumulated timing offset is Δ\Delta t = 2Ω\Omega A/c2c^2 ≈\approx 2(7.292×\times10^{-5})(2.5×\times10^{11})/(8.988×\times10^{16}) ≈\approx 4.1×\times10^{-10}\,s\mathrm s , a little over four hundred picoseconds. Gated at the one-second averaging interval conventional for this comparison, the corresponding dimensionless edge bias is s =…
