Low Energy Analysis<br />
• Subset of detectors <strong>with</strong> exceptionally good resolutions and low backgrounds<br />
• Different parameterization of event observables (independent axis)<br />
• 5 - 20 keV analysis (independent data set)<br />
• Construct 2D (EI,ER) WIMP signal PDF, including detector / analysis efficiencies<br />
• Count number of events observed inside a 90% WIMP PDF region <strong>for</strong> a given<br />
mass and cross-section (no background subtraction or background model)<br />
• Find largest cross-section that corresponds to 90% CL Poisson limit given <strong>the</strong><br />
observed number of events in <strong>the</strong> WIMP PDF region<br />
