Examples of two GCs (Δν > 0, ; left most panels), two AGCs (Δν < 0, ; centre), and two events in which Δν = 0 and (top right) or (bottom right). The phase residuals are plotted with respect to a fit of TOAs up to the event epoch t = 0. The phase residuals for the first set are shown with filled squares, and for the second set, they are shown with empty squares. The continuous lines represent the best model for the second set (Eq. (2)). For the two cases in the left (left and middle columns) the event at the bottom has a |Δν| that is much larger than the case at the top. Similarly, for the third column, the case at the bottom has a much larger than the case at the top.
