Graphical summary of the Gaussian fits to the C¹⁸O(1–0) emission in L1517. The gray scale shows the C¹⁸O(1–0) integrated intensity map of Fig. 1, and the superposed blue boxes enclose the regions where two Gaussians were fitted to the spectra. Insets with numbers 1, 2, and 3 illustrate double-Gaussian fits, while inset number 4 shows an example of the dominant single Gaussian fitted to most of the cloud spectra.
