Abstract
The Kreck-Stolz -invariant is a classic path-component invariant for the space and moduli space of positive scalar curvature metrics. It is an absolute (as opposed to relative) invariant, but this strength comes at the expense of being defined only under restrictive topological conditions. The aim of this paper is to construct an analogous invariant for certain product manifolds on which the -invariant is not defined.

Comments
Compared to the previous version of this paper, the proofs of Corollary 2.15 and Theorem 0.3 have been expanded to include more detail, greater attention is given to the role of orientation around 2.16, and some minor typos have been fixed
