I think the current policy would be to keep the COD entry, but to
remediate data according to the situation.

a/ if the original paper (if someone has a PLS, pls. share) has
*correct* coordinates, we should fix the entry and issue a new revision;

b/ if the coordinates are wrong in the original paper, we should mark
the COD entry 1524837, and add information about (linkers to) the
correct redeterminations of the structure in question. I would add
_cod_error_flag errors _cod_error_source publication to the 1524837.cif
in that case.

There is also one more sch structure, from Wyckoff, with corrections
published I guess by Pauling; I do not have the file entry handy for
now. We should follow the same procedure.

Yes, we should do that.
