Pinching rules in the chiral-splitting description of one-loop string amplitudes -- Ancillary files

Pinching-mathFile.wl -- The main file, which contains 5-point definitions and loads the data from the 6-point files below. chiralSplit_6sugra.m -- The 6-point chiral splitting correlators at 1 loop, written in terms of bilinears of homology invariants. FTlimits_6sugra.m -- Closed-string field-theory limits for all the 51 x 51 bilinears in homology invariants of the chiral six-point correlator. numerators_6sugra.m -- Gauge-theory numerators that double-copy to the six-point one-loop supergravity integrand associated with cubic graphs and contact graphs.
