***** File SOFTINFO.TXT                                                       
                                                                              
     This information file is located in the SOFTWARE directory, which        
contains source and executable code which should be of use to the IHW Archive 
user.  The SOFTWARE directory has been divided into four subdirectories:      
INTERP, IMDISP, FTB, and UTILS.  Each of these subdirectories has all of the  
necessary information to compile and/or run the programs located in that      
subdirectory.                                                                 
                                                                              
     The INTERP subdirectory contains software to interpolate the P/Halley    
ephemeris file EPHEM.TAB (in the EPHEM directory).  The source code is        
OBSNTERP.FOR (see the NOTE below), executable modules of which are called     
PCNTERP.EXE and VAXNTERP.EXE (for use in MS-DOS and VAX/VMS environments,     
respectively).  The IMDISP subdirectory contains software to display the image
and spectral data contained on the IHW CD-ROMs; this software, provided by    
PDS/JPL and improved by outside users, works only in the PC MS-DOS            
environment.  The FTB subdirectory contains software to browse FITS Tables;   
this software, provided by the Astronomical Data Center (ADC) of the National 
Space Science Data Center (NSSDC, at NASA/GSFC), runs only in the VAX/VMS     
environment.  The UTILS subdirectory contains software to concatenate separate
FITS headers and datafiles into true FITS byte streams; the software also     
works in reverse. This code, which runs only in the PC MS-DOS environment, was
provided by the IHW Large-Scale Phenomena Discipline at NASA/Goddard Space    
Flight Center.                                                                
                                                                              
                                                                              
*************  NOTE  **************                                           
                                                                              
The executable version of OBSNTERP that was placed on the Large-Scale         
Phenomena compressed image discs (Volumes 1-18) contains a small bug, and     
Archive users should not use it.  The OBSNTERP.FOR source and executable codes
placed on these discs (Volumes 19-23) have had this bug corrected.  We regret 
any inconvenience this may cause.
