Distant Geomagnetic Tail Electrons, Color Spectrogram Slides


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

Time span: 1982-10-17 to 1983-04-20


This data set contains electron energy spectra and angular distributions for 12-h periods on 35-mm color slides. The top four panels of each slide display the energy spectra averaged over the quadrants centered on the spacecraft's solar, dusk, antisolar, and dawn meridians, respectively. The bottom four panels display the angular distributions in the four energy passbands of 10 to 27, 37 to 99, 137 to 362, and 500 to 958 eV. The energy (in keV) or look angle (in deg) scales are on the right edges of the panels. The spacecraft position in GSE and SM coordinates is given every 4 h at the bottom of the slide. There are two types of solar photon-induced signals present in these spectrograms: photoelectrons associated with the spacecraft potential and photoelectrons produced internally within the analyzer.
