That looks like they are using both the transit method and the doppler method to look at each of these planets. I know that both methods are successful and have found each huge numbers of planets, but I wasn't aware that any individual planets had been found using both methods?
I would have thought that would cut down the useable number of targets a lot - does anyone know roughly what proportion of the known exoplanets have already been found using both methods?
Plus of course the difficulties of finding earth-size planets with the doppler method if the system also has Jupiter sise planets pulling the star a lot more.
