NAME
    fesdb2rdf  -- Converts Egret QVP and EXP files  into  a  single  RDF
    FITS format file.
    
    
USAGE
    fesdb2rdf qvpfile expfile rdffile
    
    
DESCRIPTION
    fesdb2rdf  reads i/p QVP and EXP (optional) data files and writes an
    o/p FITS data file in  OGIP  standard  format.
    
    The  data  is  written  in  the form of 2 BINTABLE extensions
      1) (EXTNAME = EVENTS) contains event data from the QVP file.
      2) (EXTNAME = TSI) contains information from the i/p EXP file.
    
    Extension 1 has undergone the following changes from the i/p file
      1) Time fields compressed to a single double precision value.
      2) Column order has been rearranged.                        
      3) scaling factor inposed on (x,y,z)barycenter columns.
      4) spare fields not transferred
    
    Extension 2 has undergone the following changes from the i/p file
      1) input data is in ascii format, output extension is binary
      2) format changes as required for 1) above
          ie. hex character values -> integer
              A1 logical values    -> logical
              A1 character values  -> byte
    
    
PARAMETERS
    
    qvpfile [qvp file name]
        Name of QVP file from which event data is to be taken
    
    expfile [exp file name]
        Optional input file.  Name of the exposure history file
    
    rdffile [o/p rdf file name]
        Name of the OGIP standard FITS format file to be created
    
    (exp=no) [boolean]
        Flag indicating the existance of the exposure history file
        
        
EXAMPLES
    1. Take data  from  QVPxxx.fits  and  EXPxxx.fits  and  create  OGIP
    standard file RDFxxx.fits
    
         ft> fesdb2rdf QVPxxx.fits EXPxxx.fits RDFxxx.fits
    
    2.  Take  data  from  QVPxxx.fits  and  create  OGIP  standard  file 
    RDFxxx.fits With no exposure history file...
    
         ft> fesdb2rdf QVPxxx.fits "-" RDFxxx.fits
         ft> fesdb2rdf QVPxxx.fits expfile=" " RDFxxx.fits
