Calibration ================== Accurate and quantitative 4D-STEM imaging requires meticulous calibration. 4D-Explorer includes four main steps for calibrating 4D-STEM datasets: 1. **Refinement of Experimental Parameters**: Adjust general, microscope, camera, space, and aberration parameters. 2. **Background Noise Removal**: Utilize methods like subtracting a reference background image or pixel histogram filtering. 3. **Rotational Correction**: Ensure proper alignment of the scan. 4. **Diffraction Alignment**: Correct diffraction shifts and wobbles using manual measurement, reference datasets, or FDDNet models. These steps ensure high-quality data processing and analysis. .. toctree:: :maxdepth: 2 :caption: Calibration edit_parameters/index background_subtraction/index rotational_correction/index diffraction_alignment/index
