Atomic Scattering Factors (Reflex Plus module)

Dear all,

does anyone of you know the reference of the atomic scattering factors that are used in the Reflex module?

I want to prepare a CIF for submission to the CCDC and the tags

_atom_type_scat_source

are missing. Usually in single-crystal crystallography these tags were generated by Shelx automatically and reads like

'C'  'C'   0.0033   0.0016

'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4'

etc.

Does Reflex employ the same scattering factors? Hopefully, but I can't find the reference in the Manual.

Kind regards!

Frank
