# PyTransits

A python transit synthesis program for generating synthetic lightcurves for transiting exoplanets. 

## Method

This code uses the Mandel & Agol model of transiting exoplanets. The limb darkening coefficients must be calculated separately and the following parameters must be given: 

* Orbital period (period)

* Orbital epoch (time of mid transit, epoch)

* Orbital separation (a)

* Orbital inclination (i)

* Planetary radius (rp)

* Stellar mass (ms)

* Stellar radius (rs)

* Stellar temperature (teff)

* c1

* c2

* c3

* c4

In brackets are the computational parameters.

A `PyModel` object is created with the above parameters. All must be present, otherwise the generator won't work. 

The time values are specified in JD and the model parameter is explained above. 

The return is the model flux, which is normalised so that the out of transit data is at a value of 1.
