Demonstration of how we determined which globular clusters were responsible for the gaps. The y-axis is τ, a coordinate in units of time that indicates how far ahead or behind it is from a globular cluster. The x-axis is the simulation time, t, where 0 s km kpc⁻¹ indicates the present time. The bottom plot showcases the evolution of the stream density over simulation time. We used the density to determine a suitable stream length. Subsequently, we used this length to extract a piece of Palomar 5’s orbit. This orbital segment approximates the stream. Then, we compute the gravitational force from all other stream stand-in clusters, shown in the top plot. The gravitational force is measured in acceleration and is given in integration units: km² kpc⁻¹ s⁻². Moments of high acceleration indicate the passage of another cluster. The red circles indicate the top 5 strongest passages, as well as the names of the clusters. The example shown in this plot is the same simulation as Fig. 1.
