The following automatic conversions were performed:

'_cell_measurement_temperature' value '100K' was changed to '100' -
the value should be numeric and without a unit
designator.

'_diffrn_ambient_temperature' value '100K' was changed
to '100' - the value should be numeric and without a unit designator.
