The experimental results for (epsilon_downarrow^0)/(epsilon_{F}) for the FB (green circles) and FF (red squares) mixtures are compared with the theoretically expected values for a single polaron (green and red solid lines for FB and FF, respectively). In addition, we show the energy of the dressed molecules (green and red dash–dot lines for FB and FF, respectively). Note that the theory lines are almost identical for the FB and FF cases; therefore, they overlap to a large extent. The error bars for (epsilon_downarrow^0)/(epsilon_{F}) correspond to the uncertainties of the linear fit and the errors on the Fermi energy. The error bars for X , smaller than the symbol size, represent the standard errors for each set of measurements.
