Abstract

This dataset contains simulated data used for the statistical analysis of flux-ratio anomalies in cusp-configured strongly lensed quasars. The dataset consists of two pickle files that store mock lensing predictions generated under different dark matter model assumptions. The data characterize the dependence of the $R_{\mathrm{cusp}}$ statistic on the opening angle $\phi$ for different dark matter scenarios, and form the theoretical data basis for the Bayesian inference analysis presented in the associated manuscript (arXiv:2601.16818). File description merged_by_axis_type.pklSimulated dataset based on the SIE plus external shear macromodel, including Smooth, CDM, SIDM, and FDM realizations of mock cusp lenses, grouped by cusp axis type (major-axis vs. minor-axis). merged_by_axis_type_mul.pklExtended dataset constructed from merged_by_axis_type.pkl by incorporating higher-order multipole perturbations with $m=3,4$. These files are designed to be read directly by the analysis scripts provided in the accompanying code repository:https://github.com/HouSiyuan2001/CuspDM
