Ulysses Energetic Particle Composition (EPAC)

This directory contains EPAC pulse height analysis data in 1 day (24 hr) files. Data files are provied in both binary and ascii formats which contain the same information but in a slightly different format. The file naming convention is EV92xxx (.BIN binary) or (.TAB ascii table) where the xxx is the day of 1992. Each file is described by a detached PDS label file (.LBL).

In addition to the data files, the EPAC instrument team has provided two pieces of IDL code. The file CHANTOEN.TXT contains code that will convert EPAC channel numbers to energy (MeV). The file EPAC_EV.TXT contains code that reads all available PHA data and generates a postscript plot file "epac-ev.ps". The postscript output of EPAC_EV.PRO for this data submission also included with this archive (EPAC_EV.PS). A second postscript file, (EXAMPLE.PS) shows a more fully annotated version of the output of this program for 170 days in the solar wind in 1998. In addition to the data, the annotated plot shows the theoretical traces of several atomic species (He - Fe) for comparison purposes.

GIF files have been made of the postscript provided by the EPAC team by the PDS to facilitate viewing in web browsers.
