"RED CLAY" mass-specific mineral scattering coefficient, bmin*(wavelength) in m^2/gm, 
for use by IOP (ab) routines.  These values times the concentration of mineral particles in gm/m^3 
give the scattering coefficient of the mineral particles in 1/m.  
These values are computed from Fig 4-3B and Table 3-II of Y-H Ahn, "Proprietes optiques des particules 
biologiques et minerales...," Univ. P. & M. Curie, Paris, France, 1990.  The Ahn bb* values (Fig. 4-3B) 
are divided by bb*/b* = 0.0067 (Table 3-II) to get b*.  Data were 400-700 nm.
WARNING: Extrapolated by eye and splines to 300 and 1000 nm for use in H5.0
         Spectrum may be unrealistic in the 300-400 and 700-1000 nm regions
