Mengyao Su's dataset provides 11.5 GB of 4D-STEM experimental and simulated data for evaluating and correcting projector lens aberrations in electron ptychography. The data was last updated on June 3, 2026, and is shared under a CC-BY-4.0 license. File formats include DB, TXT, NPY, PNG, CSV, and PT.
Use Cases
- Evaluating ptychographic reconstruction algorithms based on experimental 4D-STEM data.
- Correcting projector lens aberrations based on simulated and experimental data.
- Benchmarking computational microscopy techniques based on the provided 4D-STEM data.
Strengths
- Dataset size is 11.5 GB, indicating a substantial volume of data.
- Includes both experimental and simulated data, likely allowing for comparative analysis.
- Data is available in multiple formats (DB, TXT, NPY, PNG, CSV, PT) for flexibility.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for specific tasks.
