+A four-parameter fit is developed for the class of integrals known as
+the exponential integral (real branch). Unlike other fits that are
+piecewise in nature, the current fit to the exponential integral is
+valid over the complete domain of the function (compact) and is
+everywhere accurate to within $\pm 0.0052\%$ when evaluating the first
+exponential integral, $E_1$. To achieve this result, a methodology
+that makes use of analytically known limiting behaviors at either
+extreme of the domain is employed. Because the fit accurately captures
+limiting behaviors of the $E_1$ function, more accuracy is retained
+when the fit is used as part of the scheme to evaluate higher-order
+exponential integrals, $E_n$, as compared with the use of brute-force
+fits to $E_1$, which fail to accurately model limiting
+behaviors. Furthermore, because the fit is compact, no special
+accommodations are required (as in the case of spliced piecewise fits)
+to smooth the value, slope, and higher derivatives in the transition
+region between two piecewise domains. The general methodology employed
+to develop this fit is outlined, since it may be used for other
+problems as well.
