Band Width Example _ Irregular Circular Anchor Layout
NOTE:
no two anchors in the illustration above are aligned to form either a row( two or more anchors equidistant from the y- edge) or a column( two or more anchors equidistant from the x- edge). For purposes of this example, the anchor configuration above defines an“ irregular circular anchor layout” for which the“ band width” approach will be utilized. For more information on the band width approach, reference Band Width Approach for Irregular Anchor Layouts( page 38) and Special Cases for the Band Width Approach( page 42).
