Explanation of EPAM print-groups and CSV file nomenclature.
http://data.ftecs.com/VHO/VEPO/ace_epam/explanation-csv-files.html
The Explanation HTML page at Fundamental Technologies describes how the numeric data from the ACE EPAM instrument are divided into different print-groups, the nomenclature of the ASCII-based comma-separated variable (CSV) files, and how those files can be accessed.
