8. Determining the orbital period of eclipsing binaries
This tutorial contains step-by-step instructions for finding the orbital period of the Algol-type eclipsing binary (EA) GSC 04433-00065. We will discuss two methods for determining the orbital period: the EASolver method and the EEBLS method. You are already familiar with EEBLS from Tutorial 6. Comparing both methods, you will notice that EEBLS in some cases is superior to EASolver, while in other situations EASolver outperforms EEBLS.
