| top | pdf |

For some diffraction experiments, particularly for the determination of radial distribution functions, measurements are made for background scattering from the diffraction instrument and from the sample container. When this is done, the values can be included in a single loop using _pd_meas_counts_background, _pd_meas_counts_container and _pd_meas_counts_total.
