refining with anomalous scatterers

[Phoebe Rice]

1) Is there an easy way to get xplor to calculate an
    anomalous diff. map? (I have an old round-about
    way, but since I'm going to keep F+/F- separate
    this time it should be easy!)

2) Does anybody have nonbonded parameters for Cd++?
    Its not included in TOPPAR/parameter.elements.

3) We are assuming that the "IMAGinary contribution"
    to the scattering data is delta f'', and that
    c should be corrected by delta f'.  However the
    example in the manual lists some number for Fe
    which doesn't match anything in the tables (must
    be for non-standard lambda?) and has no 
    correction applied to c.  Are we assuming 
    correctly?
