        REX DOCUMENT/CODESAMPLES/ Directory Contents                          
                                                                              
                                                                              
The REX DOCUMENT/CODESAMPLES/ directory currently contains sample code, in    
five programming languages (FORTRAN, BASH, C, IDL, Python), to access the     
binary data in the REX data products in this data set.  These were developed  
for a   Linux/Unix(tm) environment, but should be portable with minimal       
effort to most command-line environments (Cygwin/Windows; OSX terminal).      
                                                                              
The greatest utility of these programs is as a set of examples demonstrating  
various techniques to read the REX instrument data products.

  Five versions of the same program, which extracts I&Q, Radiometry and Time  
  Tag binary data from REX instrument data products into a flat ASCII format; 
  the output from all five tools will be identical for Raw REX data, and will 
  show only minor differences (+/- 0.0001) for Calibrated REX data.  Refer to 
  comments in each source file for a description of its use.                  
                                                                              
  The BASH (suffix .bash), C (suffix .c) and FORTRAN (suffix .f) tools need no
  special libraries.  These three all use the filepath to a PDS label (suffix 
  .lbl), either as a command-line argument or as an input to be read.         
                                                                              
  The C (suffix .c) and FORTRAN (suffix .f) tools each require a compiler     
  (e.g. GCC and GFORTRAN to build binary executables.  See the comments       
  regarding the 'makefile' below.                                             
                                                                              
  The IDL (suffix .pro) and Python (suffix .py) scripts require interpreters  
  and supporting libraries to run.

  A file to extract the raw binary bytes of the Rex Output Frame (ROF)        
  telemetry, from the Primary Data Unit of a REX instrument data product, to a
  flat ASCII format.  Refer to the comments in this file for details.

  Two IDL files from the ASTRO FITS library for IDL; modified on the          
  development system to handle 64-bit integer data.  If a recent version of   
  the library is used, these files can probably be removed.
