Table 3: 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).
