^an = number of chromosomes sampled from each species.

^bbp = number of nucleotides in the intraspecies alignment.

^cS = the number of segregating sites.

^dπ = average nucleotide diversity at all sites.

^eπ_silent = average nucleotide diversity at silent sites.

^fFWH = normalized Fay & Wu’s H.
