LatticeQuarkProp/Vertex: Quark propagator and quark-gluon vertex with O(a) improved Wilson fermions

Data for the quark propagator and quark-gluon vertex, from lattice simulations with Nf=2 Wilson-clover fermions. Files M_hyb_*.dat and Z_*.dat are data used in figs 3 and 4 of arXiv:1809.05421. These are plain text (3 columns, legend at top of each file). VertexData.zip contains the form factors lambda_1, lambda_2, lambda_3 in the soft gluon limit, presented in arXiv:2103.02945. The content and format of the files is explained in the document VertexData_Info.pd
