Abstract: This paper contains graphs and tables of the function

$\displaystyle A{i_{p,q}}(\alpha ,x) = \int_{ - \infty }^\infty {{{(2\pi )}^{ - 1}}\exp \{ i{y^p}/p - \alpha {y^q}/q + ixy\} \;dy} $

and its indefinite integral for $ p = 3,5,7$, for $ q = 2,4,6$, and for several values of $ \alpha $ with $ \alpha \geqslant 0$. It is shown how these tables should influence the choice of an artificial viscosity for a difference scheme for a linear hyperbolic equation.
