Dataset and Source Code for: Finite digital resolution as a deterministic stabilization mechanism for dark vortex solitons across saturable media

The master executable script, named MasterSolitonAttractor.f90, contains the complete Fortran 90 source code. This program consolidates the continuous tracking invariants, inverse tracking invariants, and valid physical spatial boundaries evaluated under the paraxial approximation for all four optical materials. Upon compilation and execution using any standard compiler, such as the GNU Fortran compiler, the algorithm autonomously performs the exhaustive coordinate search and evaluates the maximum normalized propagation distances without requiring manual parameter adjustments.</p><p dir="ltr">A supplementary documentation file, named README.txt, is provided to detail the operational framework, the hardware constraints, and the exact compilation instructions required for independent verification.

Furthermore, the repository includes four pre-generated text files containing the topological stability datasets produced by the algorithm. These files are named results_Solid_CS2.txt, results_Cr_ZnSe.txt, results_GaAs.txt, and results_Ge.txt. Each text file systematically tabulates the computed residual quantization gap, the accessible digitized hardware intensity, the physical core radius in micrometers, and the resulting maximum normalized propagation distance for its respective material.

These datasets provide the exact spatial and intensity coordinates required to validate the spatial footprint and the long-range self-trapping geometries presented in the associated scientific article.</p><p><br></p>
