Abstract
We examine the limitations of the data analysis scheme for annual
modulations as a signature of WIMP direct detection. The consequences for
existing and planned experiments are pointed out. These include determinations
of optimum recoil energy regions to be analyzed for modulations and
the minimum target mass needed to detect them. Calculations for 23Na,
nat. Ge, and 129Xe as example nuclei have been performed.
