Results of BeeP analysis for Orion IRC 2. See the caption of Fig. 7 for a full description. This case is similar to that of Fig. D.2, where BeeP has reduced EST_QUALITY due to the very low parameter uncertainties. However, in this case the χ² of the Free model fit is very high, and this is clearly due to the fact that very tight constraints coming from the Planck data do not allow a satisfactorily fit to the low flux density in the IRIS map.
