UXDSUM is able to sum several patterns included in a Bruker .uxd file.

There is interest to sum these patterns only if they were recorded at the
same temperature, and in the same angular range, with the same step, etc.

Some people believe that doing 12 patterns at 2 sec/step and summing
them is better than doing one pattern at 24 sec/step.

The software is distributed with the FORTRAN source.

The executable was obtained after translation of FORTRAN to C code
by f2c, and then compilation by MSVC++2.0. It should work on Win95
and also probably Win98 and WinNT4.

It is very simple to use :
        at the program request, give the filename (without the .uxd extension)
        you will obtain the sum in
                            filenamenew.uxd

The example distributed nov23nist.uxd  is Al2O3 NIST 1976 as
measured on a Bruker D8 powder diffractometer, with slits 0.3/0.3/0.1.
