192-Sec Magnetic Field Vectors and Selected Particle Counts; Single-Orbit Plots (Digitized)


Availability: Data Identified but not Received

Time span: 1972-04-25 to 1972-05-29


This collection consists of digitized microfilm frames contains plots of 192-s averaged magnetometer data as functions of time. These data plots contain X, Y, and Z magnetic field vector components in "spacecraft coordinates," where the X axis is along the projection of the earth-sun line onto the spacecraft spin plane, the Y axis is antiparallel to the planetary motion, and the Z axis is along the spacecraft spin axis, approximately along the northward normal to the ecliptic plane. Also shown are magnetic field magnitude, the shielded counts from the Berkeley Particle Shadows and Boundary Layer experiment, and spacecraft state information. The magnetic field data were processed with Apollo 15 calibration constants and, therefore, are approximately a factor of 2 too large. For correction details, see pp. 33-43 of W. W. Lauderdale's updated Apollo Scientific Experiments Data Handbook, Aug. 1976, NASA TM X-58131, TRF B22807.

For this digitization effort the NSSDCA scanned the source microfilm collection PSFP-00219 (one reel) at a resolution of 400 dots per inch and output each frame on the film as one TIFF file. The NSSDCA also combined the TIFF images into a multipage PDF file to facilitate browsing. Both formats are included in this collection.
