... molecules

As for atoms, laboratory data for molecules are generally more accurate than computed data, but much too sparse to serve as the sole source for the computation of photospheric models or to represent the myriads of weak lines in a cool star spectrum. An overview of existing databases can be found in Allard et al. (1992); Grevesse & Sauval (1992); Gustafsson & Jorgensen (1994); Jørgensen et al. (1992); Kurucz (1992); Decin (2000). Some of these, useful for our research, are described in Decin (2000). A copy of this description can be retrieved from http://www.ster.kuleuven.ac.be/~leen. The line lists used for this research are enumerated in Paper I.

...

Each observation is determined uniquely by its observation number (8 digits), in which the first three digits represent the revolution number. The observing data can be calculated from the revolution number which is the number of days after 17 November 1995.

No more recent "near IR'' data for neutral metal lines have been added to VALD, so no improvements for this particular wavelength range could be expected over the Kurucz (1992) line lists.

... spectrum

The colour plots showing the comparison between FTS-KP and synthetic spectrum for the wavelength range 2.38-4.08 $\mu$m, may be obtained at www.ster.kuleuven.ac.be/~leen/artikels/ISO2/FTS/. Spectral ranges, for which the atmospheric contribution causes too much trouble, are omitted.
