(if any)? Let me know if you need any other system parameters. Note that the system is known to only have one transiting planet thus far.

Note that HCV-439, mentioned in the above email, was our HEK nickname for KOI-872, which later became known as Kepler-46. We used a nickname to avoid potential information leaks.

I made some initial attempts to fit the TTV signal for 439. So far I only tried co-planar systems. There are many solutions that provide a good match to the data.

The plot illustrates the importance of getting additional transits. With only one additional transit, it will be clearly possible to distinguish between the three solutions shown here. I expect that the unique solution will be found when we will have $\sim$10 transits.

This saw-tooth pattern looks to me like a short-period planetary signal which is ideal for my method (resonant oscillations would have longer period).

One solution gives normalized chi2$<$0.1 and stands out as exceptionally good. This could be the right one. It corresponds to a planet half the Jupiter mass at $a=0.29$ AU and $e=0.1$. It may or may not be the right one.

It turns out
