This dataset was used to produce the convergence plots in the paper "Numerical convergence of model Cauchy-Characteristic Extraction and Matching", as well as additional convergence tests that can be found in the repository https://github.com/ThanasisGiannakopoulos/model_CCE_CCM_public. The data can be used to reproduce the aforementioned convergence plots or for comparison against data obtained if one performs the same simulations independently.
