CURRENT CALDB MIS release

 *) bcf/clock/swclockcor20041120v002.fits
   The clock correction file used by 'swifttime' and 'barycorr' has 
   been changed to FITS format and is now stored in CALDB. 
   With the Swift software release 2.1 (Heasoft 6.0.2), the default behavior 
   of both tools has been modified to retrieve the FITS version of the clock 
   correction file from the CALDB. 
   The old ascii formatted file 'swco.dat' circulated up to now is still
   supported however new clock correction updates will be added only to the 
   FITS version of the file.   

   The FITS correction file will be updated quickly on about a bi-weekly 
   schedule, it is recommended to users to always check out from CALDB 
   the latest version of the file or set CALDB with the remote access. 
   The latest version version of the file is at 
     https://heasarc.gsfc.nasa.gov/FTP/caldb/data/swift/mis/bcf/clock/

   named as 
    swclockcor20041120vNNN.fits 

   where NNN is the version number. Use always the higher version.
