Quickstart

Although it started as a simple program, PyORBIT got increasingly complex with time. Before you start delving into the many available models, let’s work together on a few test cases to better understand the philosophy behind PyORBIT.

• In Radial velocity fit we will fit radial velocity measurements of HD189733

• In Light curve fit we will fit light curves of HD189733 from several instruments

• In Combined fit we will fit radial velocities and light curves simultaneously

My suggestion is to follow the examples in the given order for a better understanding of the many functionalities of PyORBIT.

• Radial Velocities
• Light curve fit
• Combined radial velocity and light curve fit
