Three Dimensional Plots of Flux vs Energy Displayed as Functions of Time


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

Time span: 1971-02-06 to 1974-09-09


This microfilm data set consists of machine-drawn plots of data from the Total Ion Detector (TID) part of the ALSEP/SIDE. The data displayed are 20-minute average spectra of the detector counting rates vs energy channel for all 20 channels from 10 eV through 3500 eV. A zero level is also plotted at each end of each spectrum as a reference level. Successive spectra are plotted at the appropriate intervals on an oblique time axis, resulting in a 3-dimensional plot effect. Each plot consists of 4 panels, covering local midnight to sunrise, sunrise to noon, noon to sunset, and sunset to midnight. Start and stop times of each panel are printed. The Apollo mission number and year of data appear at left center of each plot. Various charged particle regimes of the magnetosphere are readily apparent in these plots. The data in full time resolution are available on digital tape in data set PSFP-00114 (71-008C-06F).

Digitized plots of these data are available in data set PSFP-00717.
