ironman is a Python package for jointly fitting in-transit and out-of-transit radial velocities with photometric data. Its main objective is measuring the stellar obliquity of the orbit of a planet using the Rossiter-McLaughlin effect. The version of the code published here is: 1.0.2, which is the one decribed in Espinoza-Retamal et al. (2024). For more recent versions, check GitHub. Installation You can install ironman with pip pip install ironman-package Or you can download the zip file published here, uncompress it, and cd ironman pip install . Dependencies rmfit numpy scipy pandas batman-package dynesty astropy Examples To see examples of the usage of this module, see the example notebooks in the Examples folder. Example 1: How to fit data with ironman (sky-projected obliquity) Example 2: How to simulate data (e.g., for proposals) Example 3: How to fit data with ironman (true 3D obliquity) Citation If you use this code, please cite the DOI for this Zenodo repository as well as Espinoza-Retamal et al.
