Comparison between the best-fit solutions for HD 210839 by P06 (blue-dashed and orange-dotted-dashed lines) and our best-fit solutions (solid and magenta-dotted lines) for the same value of the distance (see text). Magenta diamonds are our measured FIR fluxes at 70, 100 and 160 μm. Black squares and green circles indicate flux values from the literature. For those sources in common with P06, green circles indicate new available data added to the analysis. Arrows indicate upper limits.
