Each colored curve is a strain time series randomly drawn from an example kernel with parameters k0 = 1 × 10−44, w = 3, f0 = 100 Hz, and l = 1. The kernel enforces our prior belief that deviations from GR are most likely to occur near the merger with some characteristic frequency similar to the frequency at merger.
