Ronn--

Thank you!  That's an interesting article.

They used a lot of observing time on a large telescope, and seemed to be 
really pushing the limits.

I think the trickiest part was accounting for how "sun spots" would 
affect the relative luminosity
of the parts of the star rotating towards versus away from us.  One may 
just have to give up on finding
planets with orbital periods close to a star's rotational period?
