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.

       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
