Zero-energy conductance maps show field-driven continuous reorientation transition of vortex lattice
Ta-doped sample exhibits conventional cross-shaped spatial evolution of Caroli-de Gennes-Matricon bound states
Ti-doped sample shows sharp non-split zero-bias conductance peak persisting over long distance across the vortex
Spatial evolution of non-split zero-bias conductance peak is robust against surface effects and external magnetic field
