The tape version of Kurucz's {\em Model Atmospheres}
({\em Astrophys. J., Suppl. Ser. 40, 1, 1979}) lists
the values of {\em flux moments per frequency unit} $H_\nu$, 
for a set of 342 wavelengths from 22.9 to 20000 $nm$
(229 \AA  to 20 $\mu m$). 

For each model, the tape version contains 342 values of
$H_\nu$, followed by the 342 values of 
$H_\nu^{cont}$, flux moments in the continuum.

The relation between $H_\nu$ and $F_\lambda$ (intensity per wavelength
unit ($nm$)) is

$$	F_\lambda = \frac{4c}{\lambda^2} . H_\nu	$$

which means that the values $\log F_\lambda$ listed in Table 6 of Kurucz's
paper can be retrieved by the formula

$$ \log F_\lambda = \log (\frac {1.19917.10^{18}}{\lambda^2} . H_\nu ) $$

assuming a velocity of the light of $2.997925.10^{17}$ $nm.s^{-1}$
