   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.
