You should be able to back-transform with the FT() function in the XREF
statement.  Xplor3.8 has the FT() function, but 3.1 doesn't.  READ MAP
read a map from a file, so it should be possible to go from previous MAP
scattering factors.  You might search the distributed example input
for use of the FT() function to get a good starting point.
