If data are missing in a reflection file for input, the missed data will 

not be performing in the refinement.

To check the missing data (or completeness), use "print completeness"
in the "xrefine" statement.

In order to obtain the missing data, one has to use "generate"
(see page 163 in the X-PLOR Manual version 3.1)
before reading a reflection file in the "xrefine" statement.
Then those missed data would be captured with |Fobs|=1.0
and take part in the feature performances.
