A selection among the sources for which the energy conserving approach does not produce good quality fits. We recall that those sources lie on the high L_IR end, and have bluer slopes than what is inferred by their IRX ratios. As a consequence, the difference between the free and fixed A_V solutions are significant. While the unconstrained fits (cyan) range from moderately good to very good, they underpredict the L_IR by more than 1 dex. The fixed A_V fits (red) present SEDs that are incompatible with the photometry, and in cases still do not account well for the L_IR. Colors and symbols as in B.1.
