Line intensities from IRAM observations: C/2021 A1 (Leonard) and C/2022 E3 (ZTF)

The following tables provide the line integrated intensities in K km s −1 corrected for main beam efficiency and Doppler shifts, when detected. Data in Tables 1 and 2 are average of several lines (aligned according to doppler velocity scale) of a given molecule, for lines of similar energy levels when possible.

Data in Tables 3 and 4 are provided for individual lines, averaged over one day or several days. Integrated intensities and rms are weighted average when covered by several backends, and Doppler shift measured with the backend providing the highest spectral resolution.
