Here, we expand the experimental analysis by disentangling the effects of trap inhomogeneities and the many-body continuum in one of these experiments. This makes it possible to extract the energy of the polaron at a well-defined density as a function of the interaction strength. Comparisons with quantum Monte-Carlo as well as diagrammatic calculations show goo","authors_text":"G. M. Bruun, J. J. Arlt, L. A. Pe\\~na Ardila, N. B. J\\\"orgensen, S. Giorgini, T.
