Caption: Figure 7.

Expected [C I](1–0)/¹³CO(2–1) brightness temperature ratios as a function of line-excitation temperature under the optically thin LTE condition. The four different curves respectively correspond to the case of ﹩{N}_{{{\rm{C}}}^{0}}/{N}_{\mathrm{CO}}=15﹩ (solid), 10 (dashed), 3 (dotted–dashed), and 1 (dotted).
