Unphased and phased RV data and fit for KELT-11b using the Spitzer and ground-based data together with the constraints from the Torres model relations. The black points are the Keck observations and the green squares are from APF. The apparent amplitude modulation of the red model in the unphased plot is a plotting artifact.
