Powder dictionary (pdCIF) version 1.0.1




   The 2\q diffraction angle in degrees of an intensity
   measurement where 2\q is not constant. Used if
   corrections such as for nonlinearity, zero offset etc.
   have been applied to the _pd_meas_2theta_ values or if
   2\q values are computed. If the 2\q values
   are evenly spaced, _pd_proc_2theta_range_min,
   _pd_proc_2theta_range_max and _pd_proc_2theta_range_inc
   may be used to specify the 2\q values.
