Notes. The twelve individual exposures were obtained with the G130M grating in the timetag mode (program HST-GO-11673). Central transit time was defined by propagating from zero phase on HJD 2 453 988.80339 and a period of 2.21857312 days (Triaud et al. 2009). The short exposure #0 has not been used in this work.
