The last five columns give respectively: central moment in Heliocentric Julian Days, transit duration , number of measurements within transit , mean transit time precision (see text), number of epochs E that have passed since OGLE observations, new period estimation. Note the dramatic increase in precision of the periods in comparison to the values estimated by OGLE (Table 2). Also note that period variations in the object OGLE-TR-111 (marked with *) have been recently reported by Díaz et al. (2008).
