Disk-integrated TEXES spectrum recorded on July 16, 2023, between 955.0 and 955.4 cm⁻¹ (red curve). The total error bar corresponds to a 3σ uncertainty. The broad absorption feature around 955.22 cm⁻¹ is due to a telluric water vapor line. The black curve shows the Venus spectrum, divided by the atmospheric transmission. The feature at 955.18 cm⁻¹ is an artifact, due to an overlap between two consecutive orders; it was not present in the data of March 2015, due to a different instrumental setting. Green curve: Synthetic spectrum including CO₂ only. The blue curve is the atmospheric transmission, as measured by the TEXES instrument. The slight emission of the corrected TEXES spectrum near the center of the terrestrial absorption line might suggest a slight overcorrection of the atmospheric absorption.
