<p align="justify">Eclipsing binary is one of many astronomical objects that give essential information on stellar physics. Many physical parameters and phenomena in the actual system shape the observed light curve. Eclipsing binary light curve analysis through best-model searching, known as solving the inverse problem, usually takes time for trial and error due to the numerous parameters to be adjusted and evaluated. To help the user on studying and determining an observed eclipsing binary’s parameters, we made an atlas (catalog) of various forward model eclipsing binary light curves by variating numbers of physical parameters (i, e, (Rs + Rp)/a, Ts/Tp, Rs/Rp) and starspot parameters (?, ?, f, r) on detached, semidetached, and contact systems. The catalog is used to analyze observed eclipsing binaries: ASAS ID 002257- 2039.4, KIC 6863229, KIC 9357275, TIC 272467271, and TIC 85600400. Using this catalog could help users determine the initial model to be close to the data so that the optimization process could be done more effectively. KIC 6863229, KIC 9357275, and TIC 85600400 need manual parameter value adjustment to reach the best-fitted model.
