16. There is some freedom in the choice of the phase term. An equivalent expression would be exp {i[2A(r)](r′-r)} and it would lead to the same results.
17. c2 and the pair propagator is enhanced. Provided the nodal lines of the gap function do not intersect the saddle points, the results of this paper go through without modifications.
