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 to fix the problem: https://bl831.als.lbl.gov/END/RAPID/end.rapid/Documentation/end.rapid.Manual.htm best jon
