| Abstract |
|---|
| AR Aurigae is an often observed detached eclipsing binary which can serve as a laboratory for various techniques for the time minima determination. We present a rigorous method of light curves extrema determination and compare it with the standard Kwee-van Voerden method. We discuss also causes of the discrepancies among various estimates the uncertainty of the time extrema determination and real scatter of OC values. |

| AR Aurigae je často pozorovaná oddělená zákrytová dvojhvězda, která může posloužit jako laboratoř pro různé techniky npro určování okamžiků minima. Prezentujeme rogorózní metodu určení extrému světeln křivky a porovnáváme ji se standardní Kwee-van Voerdenovou metodou. Diskutujeme též důvody diskrepance mezi různými odhady nejistoty určení okamžiku minima a reálným rozptylem OC hodnot. |
