This information has been difficult to retrieve by those familiar with the project, let alone someone not familiar with it. Fortunately, computers have greatly facilitated access to large and varied data bases, and the World Wide Web has further advanced our ability to assess and disseminate such data. Although current scientific publications use metric units, the information in these data bases are expressed in English units because that was the system used in collecting the data.
Computers allow rapid conversion to other units of measure if desired.
