                           RELEASE NOTES FOR HEASOFT 6.0.5
                                  April 26, 2006
    ******************************************************************************
    
    The HEASoft 6.0.5 release is primarily driven by the release of the Swift
    software version 2.4, but also includes updates to several tasks in the
    attitude subpackage and to the FTOOLS and XANADU utilities 'xselect',
    'extractor', 'efold' and 'fv', which have been revised to mirror the
    current development versions in use at the HEASARC. This release also
    includes CFITSIO v3.006.
    
    As before, configuration-related changes thoughout the package means that
    users who already have HEASoft v6.0X installed will need to completely
    replace their software installation; there is no clean way to simply
    overlay this new release or to update an existing installation.

    attjumpcorr [NEW TASK]- 
       Correct Swift attitude for jumps
    
    tristarid -
       Reworked match disambiguation
     
       Assorted refinements to catalog loading

                                     CFITSIO
    ******************************************************************************
    
    Version 3.006 - 20 February 2006  -(first full release of v3)
    
      - enhanced the 'col' extended filename syntax to support keyword name
        expressions like
           [col error=sqrt(rate); #TUNIT# = 'counts/s'],
        in which the trailing '#' will be replaced by the column number
        of the most recently referenced column.
    
      - fixed bug in the parse_data iterator work function that caused it
        to fail to return a value of -1 in cases where only a selected
        set of rows were to be processed. (affected Fv)
    
      - added code to fitsio.h and cfortran.h to typedef LONGLONG to
        the appropriate 8-byte integer data type.  Most compilers now
        support the 'long long' data type, but older MS Visual C++
        compilers used '__int64' instead.
    
      - made several small changes based on testing by Martin Reinecke:
        o in  eval.y, change 'int undef' to 'long undef'
        o in getcold.c and getcole.c, fixed a couple format conversion
          specifiers when displaying the value of long long variables.
        o in fitsio.h, modified the definition of USE_LL_SUFFIX in the
          case of Athon64 machines.
        o in fitsio2.h,  defined BYTESWAPPED in the case of SGI machines.
        o in group.c, added 'include unistd.h' to get rid of compiler warning.

     extractor v4.62 -
    
       Fixed bug that causes light curves from Swift UVOT data to have a TSTART
       keyword of zero and hence incorrect TELAPSE keyword.
    
     xselect v2.3 -
    
       Corrected failure to propagate MJDREFI/F everywhere it was required which
       led to incorrect label at the top of lightcurve plots.
    
       Fix so that FILTER TIME FILE works for files whose EXTNAME is either GTI
       or STDGTI. Previous version worked for GTI only, which gave an error when
       using output from maketime.
    
       Fixed so looks for the first GTI extension instead of just assuming it
       is the first extension when doing a filter time file.
    
       Fix for bug under Linux in the plot mkf command. The xparm string was being
       overwritten leading to junk being passed to plt as the label for the X axis.

    batbinevt -
       BUG FIX regarding the calculation of energy bins; the *top-most*

       Improved checking for overlapping energy bins
    
       Checking if input is a DPH of cleaned RESIDUALs (prevents erroneous
       statistical uncertainties from being calculated)
     
       Work around a BUG in XSPEC which transforms small error bars into
       big (occurs when using a PREDICTED map)
    
       Remove some Chandra Data Model keywords that become erroneous after
       binning
    
    batcelldetect -
       BUG FIX when 'nadjpix' > 1; should only affect the chi-square values
       reported
    
       New parameters 'inbkgmap' and 'inbkgvarmap' which allow pre-computed

       New parameter 'pcodethresh' which allows far off-axis sources to be
       removed (instead of having very noisy points)
    
    batoccultgti -
       Revise the parameter handling so that the use does not need to 
       know about, or delete, the required scratch files unless they want to
     
       Correct behavior for the region file coordinate system designation
    
       Add exception handling routines
