I downloaded AVE that Francisco described. It is fantastic! Nice Kwee & van Woerden minimum finder. Easy to use. Commands are mostly in English- with an occasional word or 2 in spanish - like minimo (minimum) that are easy to figure out and there is a web page with instructions in English anyway. (I don't know if I got a different version because I clicked on the English language tab on the website but it is readily useable by someone with no Spanish ability). My thanks to G.E.A. for making it available. No one who works with light curves should be without this program.
