_phasing_MIR_shell.loc

Name:
'_phasing_MIR_shell.loc'

Definition:

   The mean lack-of-closure error loc for reflections in this shell.

   loc = sum|Fph~obs~ - Fph~calc~|

   Fph~obs~  = the observed structure-factor amplitude of the
               derivative
   Fph~calc~ = the calculated structure-factor amplitude of the
               derivative

   sum is taken over the specified reflections

Type: float

Mandatory item: no


The permitted range is [0.0, infinity)
