Getting started with Astroclimes

Installation

To install Astroclimes, simply clone the GitHub repository using:

>>> git clone https://github.com/MarceloAron/Astroclimes.git

The GitHub installation comes with all of the necessary Python scripts and some exemplary auxiliary files, listed below:

  1. One model emission line spectrum from SKYCALC.

  2. A few PHOENIX model stellar spectra from the Göttingen Spectral Library.

  3. Some GGG2020 atmospheric profiles computed with ginput. For details on how to generate these atmospheric profiles yourself, check Generating GGG2020 atmospheric profiles.

  4. Publicly available CARMENES observations of Tau Boo on the night of March 26th 2018, for which the atmospheric profiles were computed.

  5. The files with the coefficients necessary to calculate the collision-induced absorption (CIA) for \(O_2\) collisions with other atmospheric particles. If needed, other coefficients are available on the HITRAN database.

  6. Some model planetary emission spectra computed with GENESIS (Gandhi & Madhusudhan 2017) with differing water abundances.

Due to their large file size, the molecular cross_sections for line-by-line absorption are not included in the GitHub repository, but can be downloaded from Google Drive. Cross-sections for other molecules not included may be provided upon request.

Pre-requisites

Before running Astroclimes, make sure you have all of the necessary Python packages installed, which are listed below. The minimum recommended Python version is 3.9. This can be done with conda environments. If you have Anaconda installed in your machine, you may do so by running:

>>> conda create --name <my_env> python=3.9

To install each package, activate the environment running conda activate <my_env> and then:

>>> conda install <package>

or

>>> conda install conda-forge::<package>

Python packages pre-requisites:

  • astropy>=5.3.4

  • corner>=2.2.1

  • emcee>=3.1.6

  • h5py>=3.12.1

  • matplotlib>=3.9.2

  • numpy>=1.26.4
