φ lines: misalignment needed to explain the measured flux ratio with respect to a certain β. β values are represented by the drawn arcs, and increase from 0.02339 (leftmost arc) up to 0.02348 (rightmost arc) in increments of 3.4 × 10⁻⁶. is the minimum needed, and φ′_max is the maximum possible misalignment angle resulting from the geometric argument (see text). The confined green area in between is therefore the possible misalignment in order to blend the counter-hotspot region by the bright core.
