v2.4.0

Version 2.4

• Adds a pytransit.EclipseModel for straightforward modelling of secondary eclipses.

v2.3.0

Version 2.3

• Brings a new transit model, pytransit.OblateStarModel for modelling transits over gravity-darkened rapidly rotating stars (Barnes 2009),
• Renames pytransit.SwiftModel to pytransit.RoadRunnerModel,
• Fixes bugs introduced in 2.2 by moving to use the Taylor series expansion to calculate the projected planet-star distances.

v2.2.3

Code cleanup and small fixes here and there.

v2.2.0

A major speed-up

• Changed to use a Taylor series based approach to calculating the planet-star projected distances. The approach is explained in Parviainen & Korth (submitted to MNRAS, 2020), and leads to a significant transit model evaluation speed-up.

v2.1.1

Made installation without pyopencl or ldtk possible. Now trying to use classes requiring OpenCL or LDTk will raise an error if the packages are not installed.

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.

PyTransit v2.0

Final release of PyTransit v2.0. However, v2.1 will be out in a day or two ;)
