\caption{Log of the TIMMI~2 observations. We list the observing date
(defined as the day on which each observing night began), time (UT),
airmass of the observation, and integration time in seconds (Cols.~3--6). The
calibrators used for the atmospheric correction are also given, with
the time and airmass of the measurements (Cols.~7--12).\label{tab:t2_fs:observing_log}}
