Reply to Hills et al. - Concerns about modelling of the EDGES data

Abstract

In our Letter, the foreground models account for a combination of astronomical foregrounds, ionospheric effects and any residual calibration effects. We obtained best-fit parameters that absorb a degenerate combination of these effects from unconstrained fits to the models. In the accompanying Comment, the concerns of Hills et al. arise primarily because they failed to recover physical values for two ionosphere parameters in a foreground model with three additional non-ionosphere parameters.
