|0010||OT And - a Long Period EA Binary with Increasing O-C|
| ||Results are compared with Crawford, R.C. et al., IBVS 2624 (1984). There seems to be indication for increasing O-C. Further observations are encouraged to improve the current elements.|
Simbad object(s): OT And,

Dear Mr. Husar, have you compared your method of minimum determination (extrem of fitted polynominals) with Kwee-van Woerden method? The results shall be the same according to error values.

Dear Mr Brat,
yes, I have made a comparison.
The Kwee-van-Woerden method agrees within the given errors. In fact for the first observation the difference was only: +0.0011 d and for the second observation: -0.0019. Especially for the second observation with the larger fluctuations the differences depend on the selection of the observations used for the Kwee-van-Woerden estimation. However: in any case it was within the given errors for the minimum timings.
Best regards, Dieter Husar
