NSSDCA ID: PSFP-00730
Availability: Data Identified but not Received
Time span: 1971-08-04 to 1972-02-03
This collection consists of digitized microfilm frames containing magnetic field data in pairs of plots. The first, or "A," plots contain 192-s-averaged X, Y, and Z magnetic field components in "spacecraft coordinates" and total field magnitude plotted against universal time for one orbit per frame. Spacecraft coordinates X and Y are in the spacecraft spin plane, with X along the projection of the earth-sun line. The Z direction lies along the spacecraft spin axis, which is nearly perpendicular to the ecliptic plane. No sensor drift corrections have been applied to the Z component of the data prior to plotting, but drifts are expected to be within +0.27 to -0.87 nT. Offset drifts are tabulated in the documentation, along with instructions on how to apply them. The second, or "B," plots contain engineering parameters, spin periods, and data from the Lunar Particle Shadows and Boundary Layer experiment (71-063D-01) for the shielded and unshielded detectors.
For this digitization effort the NSSDCA scanned the source microfilm collection PSFP-00046 at a resolution of 400 dots per inch and output each frame on the film as one TIFF file. The NSSDCA also combined groups of these TIFF images into multipage PDF files to facilitate browsing. Both formats are included in this collection.
