Hi Jon,
this is an interesting link. The quality of the absolute scales can be
benchmarked with small molecule data. As F000 for X-ray diffraction is
the sum of electrons, it can be conveniently determined from counting
when each atom is actually modelled.
Maybe this has been done, I only read th
hallo again,
thatnks for your replies and warnings about quantifying electron density. it
seems that there are fundamental uncertainties that make quantitative
measurement difficult or even impossible. however, the redoubtable david von
stetten (alias T-REXX) mentioned that "absolute maps" try t
