_pd_meas_2theta_scan

Definition:

   2\q diffraction angle (in degrees) for intensity
   points measured in a scanning method. The scan method used
   (e.g. continuous or step scan) should be specified in
   the item _pd_meas_scan_method. For fixed 2\q (white-beam)
   experiments, use _pd_meas_2theta_fixed. In the case of
   continuous-scan data sets, the 2\q value should be the
   value at the midpoint of the counting period. Associated
   with each _pd_meas_2theta_scan value will be
   _pd_meas_counts_ items. The 2\q values should
   not be corrected for nonlinearity,
   zero offset etc. Corrected values may be specified
   using _pd_proc_2theta_corrected.

   Note that for data sets collected with constant step size,
   _pd_meas_2theta_range_ (*_min, *_max and *_inc) may be
   used instead of _pd_meas_2theta_scan.
