EASolver
Patrick Wils (Vereniging voor Sterrenkunde, Belgium) developed a period search method1 that operates on photometric survey data of eclipsing Algol-type (EA) binaries. These survey data regularly are characterized by a majority of observations showing the variable in normal light, and very sparse data showing the variable in an eclipsing state. Peranso includes Patrick Wils’ method to find the periodicities of EA binaries using photometric survey data, focusing only on the observations that correspond with a faint state of the variable. The method is called EASolver, and its usage is described in Tutorial 8. The EASolver dialog box is similar to the Lomb-Scargle dialog box. (1) Patrick Wils, private communication |
