In this file we briefly describe the ancillary files.

The files Amp_1Loop.m, Amp_2Loop.m and Amp_3Loop.m contain the 1, 2 and 3 Loop N=8 super gravity scattering amplitude as described in eq. 2.1. 

The files f2.m and f3.m contain the functions defined in eq. 5.3 and eq. 5.9 respectively.

For a definition of the variables see eq. 2.2 and x=t/s.
The parameter ep is the dimensional regulator such that the space time dimension is d=4-2 ep.
The functions H correspond to harmonic polylogarithms and are described in eq. 2.7.
