§7.21 Physical Applications
►The error functions, Fresnel integrals, and related functions occur in a variety of physical applications. … ►Carslaw and Jaeger (1959) gives many applications and points out the importance of the repeated integrals of the complementary error function . …Efficient algorithms for computing the Faddeeva (or Faddeyeva) function are discussed in Wells (1999), a paper frequently cited in the astrophysics literature. … ►Dawson’s integral appears in de-convolving even more complex motional effects; see Pratt (2007). …22: 2.11 Remainder Terms; Stokes Phenomenon

…
►From §8.19(i) the generalized exponential integral is given by
…
►Two different asymptotic expansions in terms of elementary functions, (2.11.6) and (2.11.7), are available for the generalized exponential integral in the sector .
…
►Often the process of re-expansion can be repeated any number of times.
…
►For example, using double precision is found to agree with (2.11.31) to 13D.
