Examples of covers, each showing the acceptance in parameter space of color-coded patches. Each cover provides 100% acceptance for all tracks in a wedge of pixel hits. The number of patches \(n_P\) constituting these covers is 9 (top row) and 28 (bottom row), which are atypical values at the extremes of the \(n_P\) distribution (see Fig. 6). The middle plot in the bottom row shows the cover for the wedge data in Fig. 5 (right). A tertiary patch is visible as the magenta patch in the right-most column of this cover.
