Installation

Build conda environment MAGPy-RV can be run in its own environment. To generate it follow the steps:

Update dependencies in env.yml file Run the following from the folder containing the .yml file conda env create -f conda_env.yml

Package installation using pip Install pip (if Anaconda or miniconda is installe use conda install pip)

Install package
pip install magpy-rv

Examples

Examples are hosted here:

1. Simple GP Example shows the most basic code use.

2. Polynomial Model adds a model to the GP and introduces MCMC parameter search.

3. Pegasi 51b walks through the full rv analysis with a GP to model activity and Keplerians to model a planet.

4. Offset: full end-to-end pipeline to calculate 'sun-as-a-star' RVs and magnetic observables
