definition: (required) NX_CHAR ⤆
Obligatory value:
NXem_calorimetry
profiling: (optional) NXcs_profiling
Details about performance, profiling, etc.

List of comma-separated elements from the periodic table that are contained in the specimen. If the specimen substance has multiple components, all elements from each component must be included in atom_types.
The purpose of the field is to offer research data management systems an opportunity to parse the relevant elements without having to interpret these from the resources pointed to by identifier_parent or walk through eventually deeply nested groups in data instances.
CITE: (optional) NXcite

Reference to the resource which stores acquired pattern from the experiment or simulation that are analyzed in this workflow.
Can refer to the original EMD or MRC files or the parsed NXem in RDM e.g. NOMAD OASIS.

Time difference to start_time.
Collecting diffraction pattern also takes some time. It is assumed that the acquisition time for each pattern is substantial shorter than the time it takes the actuator to cause a change in stimulus (e.g. temperature).
