Extended Data Table 4 Derived physical properties of considered species

From: A solar C/O ratio in planet-forming gas at 1 au in a highly irradiated disk

  1. Columns: (1) Species; (2) Detected in emission (em) or in absorption (abs); (3) Excitation temperature (K); (4) Column density (cm−2), see details in the text on the assumptions for the size of the emitting surface in the case of emission; (5) Line Doppler broadening (km s−1); (6) Doppler shift with respect to the systemic velocity of d203-504 (25 km s−1).
