What to Cite when Using POSEIDON ================================ General Citations ----------------- When using POSEIDON in a paper, please cite `MacDonald & Madhusudhan (2017) `_ and `MacDonald (2023) `_. For multidimensional transmission spectra forward models, please cite the TRIDENT model methods paper, `MacDonald & Lewis (2022) `_. For 1D thermal emission forward model or retrievals without scattering (POSEIDON v1.0), please cite `Coulombe et al. (2023) `_. For more comprehensive emission models including scattering (from POSEIDON v1.2), please cite `Mullens et al. (2024) `_, as described below. For high-resolution cross correlation retrievals (POSEIDON v1.3), please cite `Wang et al. (2025) `_ Cross Sections (Opacities) -------------------------- For each molecule included in a model, in your methods section it is good practice to cite the specific molecular line list for each molecule's opacity. It takes our quantum colleagues *years* to make some of these line lists, so please do recognise their hard work! For convenience, we have provided a table on the `opacity database `_ page containing NASA ADS links to the relevant citation for every line list used in POSEIDON. Mie Scattering Aerosols ----------------------- POSEIDON v1.2 includes Mie scattering from compositionally-specific aerosols. When using any Mie scattering prescription in POSEIDON, please cite `Mullens et al. (2024) `_. POSEIDON's Mie scattering retrieval functionality was first used in `Grant et al. (2023) `_, but since a full description of the methodology is provided in `Mullens et al. (2024) `_ that is the preferred paper to cite for Mie scattering retrievals with POSEIDON. If you are using the v1.2 version of the aerosol database, consider also citing the `LX-MIE algorithm `_ and `PLATON `_, whose algorithms were adapted to precompute Mie-scattering cross sections. If you are using the v1.3.1 version of the aerosol database, consider citing `miepython v2.5.5 `_ and `Mullens et al. (2025) `_. The `opacity database `_ page provides extensive references for specific aerosols (e.g. refractive index sources). We also provide a comprehensive guide to our aerosol database and sources in the file `aerosol_database_readme.txt <../_static/Aerosol-Database-Readme.txt>`_. Thermal Scattering and Reflection (Giant Planets) ------------------------------------------------- When using POSEIDON for emission spectroscopy with scattering enabled or for reflection spectroscopy, please cite `Mullens et al. (2024) `_. As described in this paper, POSEIDON uses adapted forward models from PICASO, so for reflection spectra please also cite `Batalha et al. (2019) `_ and for emission spectra with scattering please cite `Mukherjee et al. (2023) `_. The underlying multiple scattering radiative transfer technique used in all these papers is described in `Toon et al. (1989) `_. Thermal Scattering and Reflection (Rocky Planets) ------------------------------------------------- If you use POSEIDON with emitting and reflecting surfaces, or use the surface albedo database, please cite Mullens et al. (2026) (in prep). Also please also cite PICASO v4.0 (`Mang et al. (2026) `_.) If you use POSEIDON for HWO applications, please also consider citing `Zelakiewicz et al. (2026) `_. Pressure-Temperature (P-T) Profiles ----------------------------------- POSEIDON includes many P-T profile prescriptions, including: * The 'Madhu' profile from `Madhusudhan & Seager (2009) `_. * The 'Guillot' and 'Dayside Guillot' profiles from `Guillot (2010) `_. * The 'Line' profile from `Line et al. (2013) `_. * The 'Slope' profile from `Piette & Madhusudhan (2021) `_. * The 'Pelletier' profile from `Pelletier et al. (2021) `_. Contribution Functions ---------------------- For contribution functions (transmission or emission), added in POSEIDON v1.2, please cite `Mullens et al. (2024) `_.
