\caption{Results of the \src\ timing analysis. The 2nd and 3rd~columns
list the Start and Stop time of each data set, the 4th the averaged IBIS/ISGRI (20--40~keV) 
source count rate  in these epochs, the 5th and 6th~columns list 
the pulse periods measured in the seven \inte\ data sets. In data sets~Nos.~2, 3, 6 and~7
the source was outside the JEM-X field of view. In data set~No.~1 only
the pulse period estimated with JEM-X is reported due to 
several telemetry gaps present in ISGRI lightcurve during this satellite
revolution, which hampered a proper timing analysis.}\label{tab:obslog}
