Introduction

  This data set comprises a reduced, subsampled set of the data returned      
  from the Apollo 15 Heat Flow Experiment from 31 July 1971 through           
  31 December 1974.  The experiment consisted of two probes placed by         
  the Apollo 15 astronauts in holes drilled in the lunar surface near         
  the Apollo 15 Lunar Surface Experiments Package site to measure the         
  thermal conductivity.  The data consist of a set of ten ASCII tables        
  with time, temperature differences, and average temperatures readings       
  measured by the thermocouples in the heat flow probes and probe             
  cables.  The data have been restored and reformatted from binary data       
  held on magnetic tapes at the NASA National Space Science Data Center       
  (NSSDC) under NSSDC ID of PSPG-00093 (old NSSDC ID 71-063C-06A).

  This single-volume dataset has been formatted according to the ISO-9660     
  level 2 Interchange Standard for directories and file names as described    
  in Version 3.7 of the PDS Standards Reference.

  All text documents and other meta information files such as descriptions,   
  PDS object definitions, and detached PDS labels are stream format files,    
  with a carriage return (ASCII 13) and a line feed character (ASCII 10) at   
  the end of the record.  This allows the files to be read by various         
  operating systems.
