Dear all,

I hope this email finds you well.

I am performing simulations of BNS mergers and utilizing the QuasiLocalMeasures thorn to plot the total angular momentum of the spacetime. However, I have noticed high-frequency oscillations in the plotted data, as shown in the attached plot. I was wondering if we should expect such oscillations. I would also like to know the reason behind such oscillations. I would appreciate if you kindly help me to understand this issue.

I am looking forward to hearing from you. Many thanks in advance!
