Yes, that's why I mentioned it specifically. I wanted you to understnd that I'm not going to say you are wrong just because you come up with a different value for the eccentricity but I will say you are wrong if, for example, the eccentricity derived from the spectroscopic data does not match the value obtained from the light curve when both are found using the Ritzian model. > So does yaw angle.

It says nothing until you correct the distance, but even a perfect match is irrelevant since the simple Ritzian model is ruled out by Sagnac, you need a better version that satisfies both. George

For all practical purposes, the end error is far too small to affect the outcome. The reason I produce only half an ellipse is that computers don't like running into x/0. There is an arctan involved. I probably COULD devise a way around it but it would amount to the same thing.

I would certainly like to compare an observed brightness curve with radial velocity. The only decent one I have is that of RT Aurigae. ..and there is a big problem. http://mb-soft.com/public2/cepheid.html Its radial velocity curve is exactly that of a star orbiting with an eccentricity of about 2.5-3. The authors claim that the cepheid actually expands and contracts in exactly the same manner. That is not impossible...but highly unlikely, in my mind. I can also produce exactly the right shaped brightness curve, with the same eccentricity. The problem lies in the fact that the phase difference I predict is not the same as the ones the authors claim. However they seem to have gone to some trouble to make the velocity curve match what they thought should be correct. They admit the velocity curve is vaguely determined. I say it is plain wrong. If you can refer me to other data like this I would be grateful. >> So does yaw angle.

If you measure with a tape laid parallel to the rod you get one value. If you measure with the same tape but laid at an angle to the rod by drawing a line perpendicular to the tape from the end of the rod, you get a different value. You are then trying to call the two different lengths along the tape the same unit of length. It doesn't matter if there are no mm marks along the tape (no measurement in seconds) the amounts of tape using the two methods differ so cannot both be called "one unit". George |
