It is not hard, I guess - you basically have to multiple the g(r)with h(x) from Eq. 7 before line 69 in <https://github.com/votca/csg/blob/master/share/scripts/inverse/postupd_cibi_correction.sh#L69> I would implement that in a similar fashion as <https://github.com/votca/csg/blob/master/share/scripts/inverse/table_switch_border.pl> which put a cos function over a table.
