PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2002-08-20 NOTE = "This file describes the Cosmic Ray data available on this DVD-R volume." END_OBJECT = TEXT END This directory contains the 15 minute averaged proton, ion, and electron flux and counting rate data from the Cosmic Ray instrument (CRS) on Voyager 2. The data were collected from the Jupiter encounter period of 7/03/79 to 8/03/79. The data are stored as 9 ASCII tables (*RATE.TAB), each containing all data provided for a specific type of data or energy range, and named according to the type of data contained in the file. Each data file has a PDS label file (*RATE.LBL) which describes properties of the data. The data files include the following: file measures units ---------- ------------------------------ ------------------------------ LD_RATE total proton + alphas flux, cm**-2 sec**-1 sr**-1 1.8-8.1 MeV LD1_RATE proton + heavy ions flux, cm**-2 sec**-1 sr**-1 nominal > 0.43-MeV LD2_RATE protons + ions counting rate, counts/sec 1.8-13 MeV LDTRP_RATE proton + alphas flux, cm**-2 sec**-1 sr**-1 3.0-8.0 MeV D4L_RATE electron counting rate counts/sec (primarily > 6 MeV) BS2E_RATE* electron flux, 8-12 MeV cm**-2 sec**-1 sr**-1 BS3E_RATE* electron flux, 5.1-8 MeV cm**-2 sec**-1 sr**-1 BS4E_RATE* electron flux, 2.6-5.1 MeV cm**-2 sec**-1 sr**-1 FPHA_RATE pulse-height analyzed proton cm**-2 sec**-1 sr**-1 MeV**-1 flux, 6 energy ranges, 1.807-8.043 MeV The asterisk-marked files (*) nominally contain two measurements, the rate with guard anticoincidence and the rate without. The experiment was in the latter state from 12:15:00, July 12, 1979, to 06:15:00, July 18, 1979. Note also that HET-I and HET-II data are averaged in these files. File content information was extracted from document [NSSDCCRS1979]. For more information please refer to that document located in the /DOCUMENT/CRS directory of this DVD-R.
