Animation 1 corresponds to Fig. 1 of Friedman+2013 for the case in which events A and B appear on opposite sides of the sky as seen from Earth (α = 180 degrees). The redshifts zA and zB of each event are changed in tandem to maintain the condition that their past light cones intersect at the big bang (τAB=0) at the end of inflation. The movie explores a portion of the parameter space in the zA-zB plane shown in Fig 3b of Friedman+2013; as zA and zB are changed while maintaining the condition τAB=0, each frame of the movie traces out a portion of the black curve in Fig 3b of Friedman+2013 corresponding to an angular separation of α = 180 degrees.
