We study Hilbert space aspects of explicit eigenfunctions for analytic difference operators that arise in the context of relativistic two-particle Calogero-Moser systems. We restrict attention to integer coupling constants g/h, for which no reflection occurs. It is proved that the eigenfunction transforms are isometric, provided a certain dimensionless parameter a varies over a bounded interval (0,amax), whereas isometry is shown to be violated for generic a larger than amax- The anomaly is encoded in an explicit finite-rank operator, whose rank increases to oo as a goes to oo.
