+ARGUMENTS

+DESCRIPTION
+This routine routines the equivlalent power series fit coefficients
+and the number of coefficients.
+
+The coefficients of either a legendre or chebyshev solution can be converted
+to power series coefficients of the form y = a0 + a1*x + a2*x**2 + a3*x**3...
+The output coefficients are scaled to the original data range.
+.ih
+NOTES
+Only legendre and chebyshev coefficients are converted. An error is
+reported for other curve types.
