2 Items needing correction

2.1 Main body of the text

In Section 2.2.2 the Merrybent detector is referred to as having a relative efficiency of 110% – this should read 100%.

2.2 Table 1

The relative efficiency and face area values quoted in Table 1 are incorrect and the volume and mass of Roseberry are slightly larger than originally quoted. The table should read as follows:

2.3 Table 3

The uncertainties quoted in Table 3 are incorrect. The table should read as follows:
