| Description | We present two methods for the determination of moments of extrema and their errors appropriate for the analysis of light variations of variable objects. The method I is suitable for determination of times of extrema of non-periodical variables or objects, whose light curves vary. The method II is apt for {O-C} analyses of objects whose light curves are more or less repeating. Both methods are displayed on the analysis of BL Cam and compared with the Kwee-van Woerden method. |
