Updated 19 Dec 2004

 Overview
    * One new file, swbpulseflt20040101v001.fits, is introduced

     NEW FILE TYPE.  Contains actual on-board pulser DAC to energy
     conversion coefficients.  The current file contains the default
     per-sandwich average coefficients.

 *  bcf/swb20020101v002.teldef

     New version, now in accord with HEASARC format recommendations;
     units of DETX/Y changed to "pixel" (NOTE: no software uses the
     units, so this is for information only)

 *  bcf/swb4ebound20030101v002.fits
    bcf/swb80ebound20030101v002.fits
