Comparison between observed (thick black line) and theoretical spectra for the SC-type star R Cmi around the spectral region of the R9(1-0) HF line. Top panel: continuous red line corresponds to the best fit (log ɛ(F) = 4.9) and black dashed lines are synthetic spectra computed with no F and log ɛ(F) = 4.2, respectively. The R9 HF, Na I and C17O lines at ~2.3358, 2.3380 and 2.3395 μm, respectively are marked. Note that the R9 line is blended to the left with a C17O line (not marked in the figure). Bottom panel: the same as in top panel showing another C17O feature used (among others) to derived the 16O/17O ratio, and the head of the 13CO molecular band from which the 12C/13C ratio was derived in some stars (see text).
