Results from TIMMI2 photometry and spectroscopy are merged in this table. The airmass and TIMMI2 integration times refer to N-band spectroscopy. Mid-IR photometry was obtained in the specified TIMMI2 filters with central wavelengths 8.6 $\mu $m (N1), 10.3 $\mu $m (N10.4) and 11.6 $\mu $m (N11.9). Errors represent the accuracy of the aperture photometry. Where no own measurements were available, e.g, for some archive data, we adapted data from (1) IRAS, (2) Wyatt et al. (2005) or (3) Perrin et al. (2006).
