Extended Data Fig. 3: Orbital decay measured with CHIMERA and KPED.
From: General relativistic orbital decay in a seven-minute-orbital-period eclipsing binary system
A quadratic fit (smooth red curve) to timing epochs exclusively originating from CHIMERA and KPED data (with the 68% confidence interval shown by the red dashed lines). This solution yielded a \(\dot{P}\) consistent with the much more precise solution derived by including PTF/iPTF data. All error bars on the timing epochs are 1σ. The time on the x axis is measured with respect to the T0 reported in Table 1.
