Posterior distributions of the population parameters governing the cosmic expansion and the CBC mass distribution. Results are shown for the resolved CBCs dataset (2 years of observations) using four detectors (orange) and five detectors (purple), and for the combined SGWB and CBCs dataset (1 year of individually resolved sources and 1 year of stochastic background) using four detectors (green) and five detectors (blue). Dashed red lines on the diagonal panels indicate injected (true) values.
