The following automatic conversions were performed:

data item '_chemical_melting_point' value '141-143' was changed to
'142.0(10)' -- the average value was taken and precision was
estimated.

data item '_exptl_crystal_density_meas' value 'not measured' was
changed to '?' -- the value is perceived as not measured.
