Find the contaminant transiting source in Kepler, K2 or TESS data.
# contaminante kohn - tah - mee - nahn - teh
A package to help find the contaminant transiting source in NASA’s Kepler, K2 or TESS data. When hunting for transiting planets, sometimes signals come from neighboring contaminants. This package helps users identify where the transiting signal comes from in their data.
## What does contaminante do?
contaminante uses pixel level modeling of the TargetPixelFile data from NASA’s astrophysics missions that are processed with the Kepler pipeline. The output of contaminante is a figure showing 1. Where the main target is centered in all available TPFs. 2. What the phase curve looks like for the main target 3. Where the transiting source is centered in all available TPFs, if a transiting source is located outside the main target 4. The transiting source phase curve, if a transiting source is located outside the main target
An example output is shown below for a target with a transiting contaminant.

Where as a transit that is centered on the target gives the following output:

## How to use contaminante
You can check out our [tutorial](https://github.com/christinahedges/contaminante/blob/master/tutorials/tutorial-1_how-to-use-contaminante.ipynb) for how to run contaminante. To run contaminante you will need a target name, a transit period, a transit center and a transit duration.
