description
This product includes proton and alpha particle flux data from the Cosmic Ray instrument on Voyager 2 from the Jupiter encounter. The data contains 15 minute averages of the proton and alpha particle flux. The data gives proton flux between 3.0 and 8.0 MeV with a small alpha particle contribution (L[1]L[2]L[3] coincidences are required). From the header data file: 07/03/79 00:00:00 to 08/03/79 23:45:00 A = (LDTRP / 4.563E-01) LDTRP = L1.L2.L3.^L4
