Plots of Reduced Magnetic Field Data on Microfilm


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

Time span: 1959-08-08 to 1959-09-10


This data set consists of linear graphs of the phase angle and semilog plots of the perpendicular field component vs time, on one reel of 35-mm microfilm. This data set contains plots of all the available reduced magnetic field data (analog and digital) obtained by this experiment. The phase angle was the angle between the component of the field perpendicular to the spacecraft spin axis and the projection into the spacecraft equatorial plane of a unit vector pointing in the direction of the sun. Data points that were derived from analog data are indicated, as is the receiving station. Data points that were derived from digital data are also indicated. In addition to the magnetometer data, the graphs contain curves representing theoretical values of the phase angle and the perpendicular field component. These were based on an eight-coefficient, spherical harmonic expansion of the geomagnetic field. The data are time ordered and have a 70% coverage for the time period indicated. Data set 59-004A-02A is also contained on this reel.
