Does the five year window refer to citations of papers published only from this period OR to citations for all recorded papers regardless of publication year?

The numbers relate to publications during the given period and citations for those papers during the same period. Or in other words, the 5 year period refers to BOTH the publication cycle AND the citation window. So, we collect data for all 5 years and citation counts within the same 5 year period.
