 The package is described in [Parviainen (2015)](http://arxiv.org/abs/1504.07433). Also, take a look at the [Bayesian parameter estimation tutorial](http://nbviewer.ipython.org/github/hpparvi/exo_tutorials/blob/master/01_broadband_parameter_estimation.ipynb) for an example on how to use the model in a basic exoplanet transit modelling situation.

 **Transit models**
   - Series-expansion based transit model by [A. Gimenez (A&A 450, 1231--1237, 2006)](http://adsabs.harvard.edu/abs/2006A&A...450.1231G).
-  - Quadratic limb-darkening transit model by [Mandel & Agol (ApJ 580, L171–L175, 2002)](http://adsabs.harvard.edu/abs/2002ApJ...580L.171M).
+  - Quadratic limb-darkening and uniform disk transit models by [Mandel & Agol (ApJ 580, L171–L175, 2002)](http://adsabs.harvard.edu/abs/2002ApJ...580L.171M).
   - Optically thin shell model by [Schlawin et al. (ApJL 722, 75--79, 2010)](http://adsabs.harvard.edu/abs/2010ApJ...722L..75S) to model narrow-band transits observations of chromospheric emission lines.
