Additional information

A number of values are available at an environmentally relevant temperatures and an number of these derive from experimentally derived data. The numbers do seem to vary a little and with no obvious reason for choosing a particular value over another, a 'rounded' figure centering on the range of values available is used as the key parameter retained.
