  The recent NA49 measurement of two-proton correlation function shows an
interesting and unexpected structure at large relative momentum. Applying
source imaging techniques to the measurement, we find an unusually steep
drop-off in the two-proton source function. We show that the steep drop-off is
due to the structure in the correlation and the drop-off cannot be explained
using conventional correlation analysis. We suggest possible physics reasons
for the unusual source function.
