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

This bundle consists of two collections of raw ASCII data, from three months
in 1975, and documentation for the Suprathermal Ion Detector Experiment
(SIDE) and the Cold Cathode Ion Gage Experiment (CCIG; also known as the
Cold Cathode Gage Experiment) which were two components of the Apollo 15
Apollo Lunar Surface Experiments Package (ALSEP). The collections are:

- Apollo 15 ALSEP ARCSAV SIDE/CCIG Raw Cleaned ASCII Data Collection 
  (1975-092 to 1975-181):  Contains 90 daily ASCII tables of raw measurements
  data acquired by Apollo 15 SIDE and CCIG instruments from 02 April to
  30 June 1975. This collection also includes one ASCII table of SIDE- and
  CCIG-related command verification 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 to
  July 1975, then cleaned for obvious bit errors.

- Apollo 15 ALSEP ARCSAV SIDE/CCIG 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 SIDE/CCIG data to ASCII for this
  archive and a one-page sheet of SIDE calibration data.
