Notes. Date UT is given for mid-points of the transits. Epoch is the transit number from the initial ephemeris given in the discovery papers. X tracks the target’s air mass during a run. Nobs is the number of useful scientific exposures. texp is the exposure time used. Γ is the median number of exposures per minute. PNR is defined in Table B.1.
