Comparison of calculated log₁₀(N_l/g_l) values for C₂HD as a function of the lower rotational quantum number J_l at different temperatures (T = 100 (solid), 300 (dashed), 500 (dotted), and 1000 (dot-dashed) K). The red lines represent the values using our calculated TIP function, while the blue lines correspond to the reference results using the HITRAN TIP function. The agreement between this work and HITRAN validates the accuracy of the current method, particularly at higher temperatures, where deviations are minimal.
