SWITch *f*

This is yet another * ad hockery* closely related to the ` PHASeless` keyword
described above. The idea in this case, is to start the calculation of a
FOM-weighted synthesis in the usual way, but when the *R*-factor reaches the value
*f*, to switch to a ` PHASeless` calculation for all reflections in the data
set. Use at your own risk.
