3.3.4.2. Description of the specimen used in the experiment

| top | pdf |

The data items in this category are as follows:

PD_SPEC [Scheme scheme3]

The PD_SPEC data items describe the specimen used to measure the diffraction data. The data item _pd_spec_preparation describes how the specimen that was used to measure the diffraction data was treated, not how the sample was prepared (PD_PREP) or characterized ( PD_CHAR).

The PD_SPEC data items are also used to describe how the specimen was mounted for the diffraction experiment. For example, _pd_spec_mount_mode and _pd_spec_orientation describe the measurement geometry, while _pd_spec_shape and _pd_spec_size_* describe the specimen shape and size.
