Description

This descriptor identifies an ensemble of 8 data sets of EPAM count rates averaged over 1-day intervals in each of several energy bins. One data set (PG65) has spin-averaged rates while the other 7 have rates in each of 4 or 8 spin sectors. Each of the 7 sectored data sets is specific to a given one of the several EPAM instruments (apertures). Each of the 8 data sets is individually described in the VHO/VEPO interface at https://vho.gsfc.nasa.gov.

Description

The Explanation.html page at Fundamental Technologies (FTECS) describes how the numeric data from the Ulysses HISCALE instrument are divided into different print-groups (referred to as "data sets" above), the nomenclature of the ASCII-based comma-separated variable (CSV) files, and how those files can be accessed. Owing to their great similarities, "this file works for both EPAM and HISCALE." - TPA
