Fig. A.1.


Carbon recombination lines between 80 GHz and 116 GHz detected with the IRAM 30 m telescope toward the Orion Bar (DF position). The dashed lines indicate the LSR velocity (10.7 km s−1) of the molecular gas in the PDR. The red and green curves show Gaussian fits to the Cnα and Henα lines, respectively. We use these fits to determine the contribution of He recombination line wings to the emission observed in the velocity range of the Cnβ and Cnγ lines. We note the different abscissa and ordinate axis scales.
