Mass Spectrometer Data as Formatted Outputs (Digitized)


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

Time span: 1972-04-20 to 1972-04-24


This collection contains digitizations of formatted outputs of the data imaged on microfilm. The format presents sequential pairs of mass spectra (high- and low-mass channels) along with background, peak amplitude, housekeeping, and trajectory data. In addition there are some tabulated summaries of peak amplitudes, trajectory data, and housekeeping measurements as a function of ground elapsed time (GET). Each summary chart covers several hours of experiment operation.

For this digitization effort the NSSDCA scanned the source microfilm (PSPA-00139) at a resolution of 400 dots per inch into TIFF files and output one TIFF image file for each frame on the film. The NSSDCA also combined groups of these TIFF files into multipage PDF files to facilitate browsing. Both formats are included in this collection.

Also available from the NSSDCA is the magnetic tape of the Apollo 16 Mass Spectrometer data (PSPA-00098) used to generate the formatted outputs.
