About this site

This site publishes the research results of the Eos Project.  The results, including software Eos and Orikoto programs, are freely used only if

  • Free ones are used for academic purposes, and
  • the authors and copyright holders are appropriately cited.

We may remove the data  for several reasons,  such as

  • Eos newer versions are available.
  • We cannot maintain old versions, and as a result, the programs that run on the old version of Eos.
  • The data that we refer to on this web are also adequately cited.
