orbits 0.1.0

Orbit fitting with PyMC3 and exoplanet

# orbits

WARNING: This is still in early development. See the [Initial release milestone](https://github.com/vandalt/orbits/milestone/1) section for details.

Currently, only the RVModel is available. _orbits_ also provides functions to load PyMC3 parameters and define GP kernel.

_orbits_ is a wrapper around [exoplanet](https://github.com/exoplanet-dev/exoplanet) aimed at providing pre-defined orbit models that can be quickly setup from the API or from a configuration file. The goal is to have something similar to [RadVel](https://github.com/California-Planet-Search/radvel), but using exoplanet and PyMC3 as a backend.

The 0.1 release supports creating an RVModel with a parameter dictionary, defining GP kernels, and using the RVModel object for inference.

## Installation

_orbits_ can be installed with pip: python -m pip install orbits.

To use the development version of _orbits_, clone the repository and install it: `shell git clone https://github.com/vandalt/orbits.git python -m pip install -U -e ".[dev]" `

## Using _orbits_ There is no detailed documentation yet, but examples will be added to the examples directory. There is currently an example with the K2-24 dataset. This replicates tutorials from _exoplanet_ and _RadVel_.
