Overview for helios_e7_trainor We describe first SPDF-resident Helios 1 and 2 E7 (Trainor, LaL) data that are ftp-accessible and then those that are accessible with graphical display and parameter subsetting via FTPBrowser. There are multiple Helios E7 data sets ftp-accessible from ftp://spdf.gsfc.nasa.gov/pub/data/helios/helios1/particle/e7_trainor/ Hourly fluxes of protons with energies 3.3-21.6, 21.6-57.0, and >57.0 MeV are accessible at ftp://spdf.gsfc.nasa.gov/pub/data/helios/helios1/particle/e7_trainor/h-a-pf.asc They are described at ftp://spdf.gsfc.nasa.gov/pub/data/helios/helios1/particle/e7_trainor/h-pf.txt 30-min fluxes of protons in 7 energy bins from 3.40-6.05 MeV to 135-206 MeV and of alpha particles in 6 energy bins from 3.20-4.98 MeV/n to 45.5-57.5 MeV/n are included in this data set. 32 30-min count rates are also included.in each record. These data are described at ftp://spdf.gsfc.nasa.gov/pub/data/helios/helios1/particle/e7_trainor/original/aareadme_helios1_e7_org.txt A subset of these "original" data is given in the "subsetted" data at ftp://spdf.gsfc.nasa.gov/pub/data/helios/helios1/particle/e7_trainor/subsetted/ The subset consists of the 13 proton and alpha particle fluxes and two count rates of 2-4 and 4-8 MeV electrons. Note that Helios B (Helios 2) data may be retrieved by using the Helios A url's above, substituting "Helios A" (or "1") with "Helios B" (or "2"). Note also that FTPBrowser interfaces with parameter subsetting and graphical display are available for the 30-min Helios E7 data at http://omniweb.gsfc.nasa.gov/ftpbrowser/helios1_e7_30min.html and http://omniweb.gsfc.nasa.gov/ftpbrowser/helios2_e7_30min.html --------------------------------------------------------------------
