_phasing_MIR_der_shell.fom

Name:
'_phasing_MIR_der_shell.fom'

Definition:

   The mean value of the figure of merit m for reflections for this
   derivative in this shell.

       int P~alpha~ exp(i*alpha) dalpha
   m = --------------------------------
             int P~alpha~ dalpha

   P~alpha~ = the probability that the phase angle alpha is correct

   int is taken over the range alpha = 0 to 2 pi.

Type: float

Mandatory item: no

The permitted range is [0.0, infinity)
