Page 544: in Eqn (11) M^2 should be replaced by M.
Page 550: Eqn (33) should read \Omega = (V_0 / \hbar) \partial \epsilon_I / \partial L + \omega_\perp
Page 559: '...provided f(x) is a smooth function with a simple minimum at L^*...' should read:
'...provided f(x) is a smooth function, such that the total energy has a simple minimum at L^*
Page 560: f(x)=x/4 should read f(x)=-x/4.
Page 613, Eqn(B2): \phi'_\beta should read \phi^*_\beta.
Please let me know if you spot any other typos/errors in the paper.
