Uniform automated analysis of Sdiff splitting due to lowermost mantle anisotropy: Caveats and curated global dataset

Summary Seismic anisotropy, the dependence of seismic wave speeds on the direction of propagation and/or polarization, places crucial constraints on deformation and convective flow in the lowermost mantle (the D″ layer). Shear waves that diffract along the core-mantle boundary (C...
