The last five columns give respectively:
central moment in Heliocentric Julian Days, transit duration $t_{\rm tr}$,
number of measurements within transit $N_{\rm tr}$, mean transit time
precision $\delta_{\rm tr}$ (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 \cite{diaz08}.
