Exoplanet population inference
==============================
This repository contains the code and text for the paper [Exoplanet population
inference and the abundance of Earth analogs from noisy, incomplete catalogs](
http://arxiv.org/abs/1406.3020)
by Daniel Foreman-Mackey, David W. Hogg, and Timothy D. Morton and submitted
to ApJ.
The code lives in the `code` directory and the LaTeX source code for the paper
is in `document`.
**Code**
The meat of the probabilistic model is implemented in `population.py`. Then
there are a set of scripts that you can use to generate the figures from the
paper. You should look at the docstrings for details but the summary is:
* `simulate.py` generates synthetic catalogs from known occurrence rate
density functions,
* `main.py` does the MCMC analysis on either real or simulated catalogs, and
* `results.py` analyzes the results of the MCMC, makes some figures, and thins
the chain to the published form.
Results
-------
Our simulated catalogs and results are [available online on figshare](
http://dx.doi.org/10.6084/m9.figshare.1051864).
