The data files are for:

Figure 1 - Near-IR spectra for a 4.13 x 10^18 H2O cm^-2 sample deposited at 21 K and warmed to 150 K as a function of temperature

	Figure 1 - DB1+DB2.txt: the first column is wavenumber (cm^-1) and the next nine columns are optical depth spectra for films taken at 21, 30, 50, 70, 90, 110, 130, 150 K, and 21 K (crystalline).   
        The spectra in this region have been multiplied by 0.1 for ease of comparison in a single plot. 

	Figure 1 - DB3+DB4+DB5.txt: the first column is wavenumber (cm^-1) and the next nine columns are optical depth spectra for films taken at 21, 30, 50, 70, 90, 110, 130, 150 K, and 21 K (crystalline).
	   
	Figure 1 - Full Spectrum - prior to vertical shift and scaling: the data in Figure 1 before vertically shifting the spectra but after correcting for water vapor.  
	Note these spectra extend down to 2000 cm^-1.
