| contents | <p>The following data corresponds to correlated-k tables (1), continua (2) and CIA (3) provided by Chaverot et al. (2025). Please refer to the article for additional information. </p> <h3><strong>1) Correlated-k tables</strong></h3> <p>We provide a total of 8 new correlated-k for various gas mixtures, based on the HITRAN 2020 database for H2O and CO2 linelists. The tables are given at a relatively high resolution (R=500), and in the Exo_k format (<a href="https://perso.astrophy.u-bordeaux.fr/~jleconte/exo_k-doc/index.html">see here</a>) to allow users to convert them to their favorite format. </p> <p>For each table, the absorption has been calculated from 10cm-1 to 30'000cm-1 with spectral steps equal to 0.001cm-1. For H2O+N2+CO2 gas mixtures, the CO2 content as been fixed as a fraction of the N2 pressure (376ppm, 1000ppm, 2000ppm, 0.1, 0.5, or 0.75). In these cases, the volume mixing ratio (vmr grid) corresponds to the water pressure divided by the total pressure (H2O+N2+CO2). For the CO2+N2 table, the vmr corresponds to the CO2 pressure divided by the total pressure. For the H2O+CO2 table, the vmr corresponds to the H2O pressure divided by the total pressure. </p> <p>Pressure grid (Pascal): [1, 10, 1e3, 1e4, 1e5, 1e6, 1e7]</p> <p>Temperature grid (Kelvin): [50, 110, 170, 230, 290, 350, 410, 470, 530, 590, 650, 1000]</p> <p>Volume mixing ratio (vmr) grid: [1e-6, 1e-5, 1e-4, 1e-3, 1e-2, 0.1, 1]</p> <p> </p> <h3><strong>2) Continua</strong></h3> <p>For the three considered mixtures, continua are calculated using linelist from HITRAN up to 400K and HITEMP 2024 beyond.
