The Data Center now includes an area where Researcher Contributions can be downloaded. Researcher Contributions are files specifically related to CSES which have been prepared by individual researchers and made available to the public. The first such contribution is the “CSES Module 1 and Module 2 Macro Booklet” (July 5, 2005 version) by Ana Espírito-Santo, Diogo Moreira, André Freire, Marina Costa Lobo, and Pedro Magalhães.
