_pd_calc_intensity_

Names:
'_pd_calc_intensity_net' '_pd_calc_intensity_total'

Definition:

   Intensity values for a computed diffractogram at
   each angle setting. Values should be computed at the
   same locations as the processed diffractogram, and thus
   the numbers of points will be defined by
   _pd_proc_number_of_points and point positions may
   be defined using _pd_proc_2theta_range_ or
   _pd_proc_2theta_corrected.

   Use _pd_calc_intensity_net if the computed diffractogram
   does not contain background or normalization corrections
   and thus is specified on the same scale as the
   _pd_proc_intensity_net values.

   Use _pd_calc_intensity_total if the computed diffraction
   pattern includes background or normalization corrections
   (or both) and thus is specified on the same scale as the
   observed intensities (_pd_meas_counts_ or _pd_meas_intensity_).

   If an observed pattern is included, _pd_calc_intensity_
   should be looped with either _pd_proc_intensity_net,
   _pd_meas_counts_ or _pd_meas_intensity_.
