C abundances as a function of temperature from the C I lines in the H band (green circles), and the forbidden [C I] line at 8727.14 Å (empty triangle). The shaded green region is the corresponding best-fit ±1σ trend of the C I lines, while the shaded red region is the best-fit ±1σ trend of theCO lines. The large black dot marks the intersection of the two curves, and its x-coordinate provides the best-fit temperature.
