283960 (current)	2023-05-23	cif/9/ (saulius@tasmanijos-velnias) Estimating atom types and attached hydrogen counts for all range 9 COD entries. Atom types and hydrogen counts for about 170 entries were adjusted manually after running 'cif_guess_AMCSD_atom_types'. Commiting only those entries where declared and calculated summary formulae are matching exactly. To get the reduced formula, the Z value was estimated with 'cif_estimate_Z' after atom type adjustment. NB.: some files still do not contain the Z value, since the Z that was written into the files was estimated before the atom type correction was made, not after. The Z values will be recomputed once more after the atom types are checked in.	9017784.cif
