Solar Wind Energy and Mass Spectra Plots+ Lists in Sun-Synch Mode on Microfiche


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

Time span: 1977-11-11 to 1978-11-22


This data set consists of microfiche containing hourly averages of counting rates for individual mass and energy steps, presented in the form of plots and lists. For each hour of sun-synch data and each sensor there are two projected three-dimensional plots, one contour line plot, and one list, all representing the same set of data. The boldfaced letters and numbers on the top of each fiche are internal codes used during fiche production and bear no significance to the data. The microfiche are read column by column, top to bottom. The upper left-hand panel indicates the orbit number and the time interval during that orbit for which data are available. This panel is followed by two to three panels with remarks, including a graph of the orbit segment that was traversed during the indicated time interval. Following these panels there are plots and lists, i.e., a panel with plots followed by one to two lists corresponding to the plots. The times indicated do not always start and stop at a full hour; the start time shows the beginning of the first record found on the data tape after the previous full hour. This need not be a record with useful solar wind data. The stop time indicates the last record with useful solar wind data during this hour. If a full hour period is missing, there was a data gap larger than an hour. For each data period the fraction of time for which solar wind data are available is shown. This indicates the total time of all records (on the data tape) that contained any useful data (one record equals 63.7 s). Occasionally, records are not filled to 100 percent with useful data; therefore, time of actual data coverage may be slightly, but not much, smaller than the time indicated. Except for this, panels of plots and lists are self-explanatory.
