In order to perform Bayesian parameter estimation to infer the sourceproperties of gravitational waves from compact binary coalescences (CBCs), thenoise characteristics of the detector must be understood. It is typicallyassumed that the detector noise is stationary and Gaussian, characterized by apower spectral density (PSD) that is measured with infinite precision. Wepresent a new method to incorporate the uncertainty in the power spectraldensity estimation into the Bayesian inference of the binary source parametersand apply it to the first 11 CBC detections reported by the LIGO- VirgoCollaboration. We find that incorporating the PSD uncertainty only leads tovariations in the positions and widths of the binary parameter posteriors onthe order of a few percent. Our results are publicly available for download ongit [1].
