Reduced and Analyzed Martian Occultation Data (Tables and Plots) on Microfilm


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

Time span: 1971-11-14 to 1972-10-26


This data set contains both reduced and analyzed data on 16-mm microfilm. The reduced data are tables and plots of observed frequency and residuals (both raw and smoothed) versus time. The analyzed data include tables and plots of derived electron density, plasma scale height, plasma temperature, mass density, number density, temperature lapse rate, pressure scale height, pressure, and temperature versus radius from the center of mass of the planet Mars. Most of these items are also listed and plotted versus altitude from the surface. The spacecraft orbit number, day of year, and start-stop times are also given for each occultation. Geodetic coordinates (latitude, longitude, surface radius, parameters referenced to a reference ellipsoid) are also given for each occultation. Data are included from the standard mission (orbits 0 to 79), the first extended mission (orbits 352 to 450), and the second extended mission (orbits 638 to 696).

Digital images (scans) of the entire contents of the microfilm are available as data collection PSPA-00637.
