Bundle Overview
===============

This bundle consists of two collections of raw ASCII data, from three months in
1975, and documentation for the Heat Flow Experiment (HFE) which was one
component of the Apollo 15 Apollo Lunar Surface Experiments Package (ALSEP).
The collections are:

- Apollo 15 ALSEP ARCSAV Heat Flow Experiment Cleaned ASCII Data Collection
  (1975-092 to 1975-181):  Contains two ASCII tables of raw science
  measurements acquired by the Apollo 15 HFE from 2 April through 30 June
  1975: one table provides Mode 1 (Gradient) data while the other table
  provides Mode 3 (Housekeeping) data. This collection also includes ASCII
  tables of HFE-related command verification and raw analog housekeeping
  data. These ASCII files are transformations of raw binary data extracted
  from NASA's original daily Apollo 15 ALSEP Archive Tapes (known as ARCSAV
  tapes) spanning April through June 1975, then cleaned for obvious bit
  errors.

- Apollo 15 ALSEP ARCSAV Heat Flow Experiment Raw Cleaned ASCII Document
  Collection (1975-092 to 1975-181):  Contains a document that describes the
  ASCII products in the data collection above. It explains the file formats
  and references publications that are relevant to understanding these data.
  This collection also includes the Fortran programs used by the data
  provider to transform the raw binary HFE data to ASCII for this archive.
