One of the terms in the sum has components only in the top two rows, the other only in the bottom, and they need a separate sign-factor. So we should add the possibility to have a complex zero to our integer mapping in make_gammas? The switch statement would become a little bit more messy then, since it will depend on two signs.\r\nPerhaps another idea might be, since this doesn't affect the majority of all mesons, to add a third column to the gammas, re-introducing the proper complex phase? But then there is the speed issue once more.\r\n\r\nCheers\r\nAnthony"}}
