What is in the file
One row per researcher, in rank order. The columns are: rank, name, institution, country, the researcher's rank on each of the four member problem directories (gb_rank Goldbach, leg_rank Legendre, n2p1_rank n2+1, tp_rank twin primes), the member problems they appear on, topical paper and citation counts, h-index, and first and last active year. A member-rank cell is left blank when that member directory does not list the researcher (see Methodology).
