PyTransit 2.1

PyTransit 2.1

Version 2.1 adds a new fast transit model SwiftModel. This model can use any radially symmetric function to model stellar limb darkening while still being faster to evaluate than the analytical transit model for quadratic limb darkening. The model is detailed in Parviainen (submitted to MNRAS, 2020), and examples using the model can be found under the notebooks/swift directory.
