What is an o-c curve? How do you find a calculation of a star?

In class today I was looking over some of this information. I didn't get to far into it because i didn't really have time because i was searching for a star that we might be able to observe tomorrow.. oh boy will it be cold! i'll continue to do this tomorrow in class.

At home, i started to type out an outline of what i've read in __A Tour of the Subatomic Zoo__ i have yet to finish it all. I only got through chapter 2 and will probably start typing the rest up tomorrow or this weekend. Probably this weekend since tomorrow will be a busy day for me because of my game and late night observing..

I'm an answering one of my questions from yesterday about the o-c curve. "The changing period of the system could then be observed by plotting an O-C (observed minus calculated) curve." [|reference] Basically, what this is saying is that an o-c curve is the magnitude of what you observed minus your prediction of what the magnitude is supposedly suppose to be.
