Abstract: Tools to calibrate a (scanning) transmission electron microscope from data, with a focus on 4D STEM. Recovers the geometric calibration of a 4D STEM experiment, including scan and detector rotation, handedness, camera length, scan pixel pitch, overfocus and descan error, using a differentiable digital twin of the microscope built on TemGymCore and JAX.
