PROFILE

Lutz Althüser

Developed rotated 2D map interpolation support for the XENONnT/straxen repository, enabling accurate data interpolation across rotated coordinate frames to enhance calibration and event reconstruction workflows. The implementation introduced a new 'rotated' option within InterpolateAndExtrapolate and InterpolatingMap, leveraging Python for scientific computing and advanced data interpolation. The approach combined Linear1Din2D interpolation—applying linear interpolation along one axis and nearest-neighbor selection along the other—to address the challenges of rotated geometries. This feature reduced manual preprocessing and improved data fidelity, supporting smoother research processes for scientific users working with complex coordinate systems and high-precision experimental data.
