_pd_meas_counts_

Definition:

   Counts measured at the measurement point as a function of
   angle, time, channel or some other variable (see
   _pd_meas_2theta_ etc.).

   The defined fields are:
     _pd_meas_counts_total, scattering from the specimen
       (with background, specimen mounting or container
       scattering included);
     _pd_meas_counts_background, scattering measured
       without a specimen, specimen mounting etc., often
       referred to as the instrument background;
     _pd_meas_counts_container, the specimen container or
       mounting without a specimen, includes background;
     _pd_meas_counts_monitor, counts measured by an 
       incident-beam monitor to calibrate the flux on the 
       specimen.

   Corrections for background, detector dead time etc.
   should not have been made to these values. Instead use
   _pd_proc_intensity_ for corrected diffractograms.

   Note that counts-per-second values should be converted to
   total counts. If the counting time varies for different
   points, it may be included in the loop using
   _pd_meas_step_count_time.

   Standard uncertainties should not be quoted for these values.
   If the standard uncertainties differ from the square root of
   the number of counts, _pd_meas_intensity_ should be used.
