Data deposit for "Short communication: Continental-scale drainage divide analysis with pydivide"

Version 4. Daniel Peifer, Graduate Program in Geography, Institute of Geosciences, Federal University of Minas Gerais, Belo Horizonte, Brazil. This deposit holds the results reported in the paper and its supplement, the programs and settings that produced them, the MATLAB reference exports used for validation, and the instructions for rebuilding the inputs that cannot be redistributed. Every pydivide result was computed with pydivide 0.2.1 (Peifer, 2026, https://doi.org/10.5281/zenodo.23617104; git tag v0.2.1, commit 9abadce606c570ec7d27997865fe39257470a482). The reference results come from TopoToolbox 3 for MATLAB at commit 1bc93e7 with the four patches in reference_patches_S1.zip.
