Caption: Figure 12.

Top: a preliminary local background model, anchored to the same point as in Figure 11. Circled points have been iteratively rejected as too high, given the modeled noise level (Section 3.2); the larger points were not rejected. Middle: final local background models, originally, but no longer, anchored to every point in the scan. Bottom: global background model, constructed from the final local background models (solid curve) and from quadratic, instead of linear, local background models (dashed curve).
