DATA OF
Querry M. R., Wieliczka D. M., Segelstein D. J. 1991. [Refractive index of] Water (H2O). In: Handbook of optical constants of solids. Palik, E. D. (ed.). Academic Press, New York, pp. 1059-1077.			

NOTES
m' - real part of the refractive index (m = m' - im") relative to that of vacuum
m" - imaginary part of the refractive index (m = m' - im") relative to that of vacuum
All DATA have been obtained by the data authors for the following conditions:
m' - obtained by Segelstein D. J. (1981. The complex refractive index of water. M. S. Thesis, University of Missouri, Kansas City) through a subtractive Kramers-Kronig analysis of the imaginary part of the refractive index			
m" - obtained by one of the data authors (Segelstein D. J. 1981) by compiling selected existing data	
	
The absorption coefficient, a, (column CALC) has been calculated by Jonasz M. (MJC Optical Technology, www.mjcopticaltech.com) from the imaginary part, m", of the refractive index published therein, by using the following formula: a(lambda) = 4 PI m"(lambda) / lambda, where lambda is the wavelength of light in vacuum.			

Underscore (_) marks the absence of or incomplete data		
Each column is separated by a TAB - when you import the file into a spreadsheet all column headings should be aligned with the numbers.
