The general problem of determining the N-metal pair potential from tunneling characteristics of proximity effect N-S sandwiches is assessed, and two specific methods are presented. These methods are applied to the treatment of data on PET junctions of the form In-Al2O3-Al/Nb. Inclusion of the influence of the Nb-induced Al pair potential produces important corrections to Nb properties (α2F(E), λ, Μ*) initially obtained by neglecting this influence.
