Extended Data Table 2 Details of the QPO in 2–10 keV XMM-Newton Data

From: Millihertz oscillations near the innermost orbit of a supermassive black hole

  1. All uncertainties represent the 1σ confidence interval. aCentroid frequency of the QPO, as measured from fits with an additional Lorentzian for the QPO (with the power-law broadband noise model). bp-value from the SSE significance testing, assuming a power-law broadband noise model. cp-value from the SSE significance testing, assuming a Lorentzian broadband noise model (centroid frequency = 0). dp-value from the AIC significance testing, assuming a power-law broadband noise model. ep-value from the AIC significance testing, assuming a Lorentzian broadband noise model (centroid frequency = 0). fQuality factor of the QPO, defined as Q = fQPO/FWHMQPO, as measured from fits with an additional Lorentzian for the QPO (with the power-law broadband noise model). gFractional RMS of the QPO, as measured from the normalization of the additional Lorentzian for the QPO (with the power-law broadband noise model).
