Survey Plots of all Detectors, 24-Hours of Data Per Plot, on Microfilm


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1973-10-30 to 1976-03-15


This data set contains reduced data supplied by the PI, and is on 16-mm microfilm. The data are a series of plots of flux vs time, with each plot covering 1 day (24 h). Each plot is identified by the year, day number, and satellite (IMP-J). The location of the spacecraft at noon (GMT) is given in both solar ecliptic coordinates and solar magnetospheric coordinates. Universal time, in hours, is plotted along the abscissa. Five different plots contain the data for each day. The first plot shows the fluxes of 0.4 MeV protons, 3 MeV protons, 3.5 MeV alphas, and 2 MeV medium-Z particles, in units of the log of the flux in number/(sq cm-s-sr-MeV/nuc). The second plot shows fluxes for detectors E5, E6, GM3, and the E4 telescope in units of the log of the flux in number/(sq cm-s-sr) for energies above the detector threshold. The third plot shows the solar X-ray flux in 1 to 11 A, 4 to 16 A, and 2 to 10 A passbands in units of the log of the flux in ergs/sq m-s. The fourth plot shows: (a) the log of the ratio of the count rates of detectors E28 and E2C, (b) and (c) the amplitude and phase of a cosine fit to the 0.4 MeV proton fluxes and 0.2 MeV electron fluxes, (d) the log of the alpha to medium-Z particle fluxes (1.6 to 4.3 MeV/nuc) and the log of the ratios of the proton to alpha fluxes (1.74 to 4.3 MeV/nuc). The fifth plot shows the counting rates of the two scintillators used to remove the penetrating particle background from the other detectors.
