Remarks

28 Jan 2013: A second planet is perhaps present in the system, infered from TTVs (Maciejewski et al. 2013)
20 Mar. 2010: Campo et al (2010) have observed two secondary transits, leading to a precession rate for ω of ω'=0.02 deg./day.
Warning: The period given in the table is the present sideral period Ps.
For the calculation of future transit ephemeris TE, observers should use eqs. (7) and (8) of Campo et al. 2010.
