My apologies as well about the incomplete James perusal. I was just looking
for either term in the table of contents, and assumed that a similar meaning
would apply to such a similar (identical) term. Perhaps there are some
structures in the PDB, then, that have Jamesian structure amplitudes?

I'll add my 2 calories then. Gerard's new naming carefully avoids the
"Factor" and "Amplitude". The following term should get everybody to
agree:
"FA-free STRUDL".
Example of politically correct use:
"It is good practice to deposit your FA-free STRUDL in the Protein Data
Bank along with the atomic coordinates"

Dear Gerard,
As usual, your contribution is a hard act to follow. However, given
that your actual proposal can be rather indigestible (especially with
lots
of cream) we might have to stick with the current options.
What the perusal of James has revealed is that, if we want to
respect
the terminology that Ewald and he introduced, "structure amplitude" and
"structure factor amplitude" cannot be considered as synonyms - which
finally answers Bernhard's question, Google results notwithstanding.
With best wishes
Gerard.
