| 2019 Scrolls 5.5TB | 7.91µm 3D X-ray scans of two intact scrolls (top halves only), scanned in horizontal slices from bottom to top. Each half scroll scan is 14,000 .tif files, 120MB each. Each slice is 7.91µm tall, so this scroll half is 11.2cm tall. Both were scanned at 54keV, though we also released a smaller “slab” of Scroll 2 at 88keV. These are the scans used to win the 2023 Grand Prize.    |
| 2023 Scrolls ?TB (still processing) | New scans from 2023 (announcement). 3.24µm and 7.91µm 3D X-ray scans of two partially unrolled scrolls, scanned in horizontal slices from bottom to top. Each scroll scan is ~25,000 .tif files, 170MB each. Each slice is 4µm tall, so each scroll is ~8cm long. Both were scanned at 53/70/88/105keV, for a total of 2*4=8 volumes each. Being released on an ongoing basis, as the data is being processed. Can also be used to win prizes.   |
| Segments 300-400GB | Segmentation is the mapping of sheets of papyrus in a 3D X-ray volume. The resulting surface volumes can be used directly to look for ink.  |
| Fragments 2.4TB | 3D X-ray scans, infrared images, and hand-labeled ground truth ink masks for detached scroll fragments. Each fragment scan is 7,000-14,000 .tif files. The 2019 scans (fragments 1-4) are 3.24µm and 54/88keV. 2023 scans (fragments 5-6) are 3.24/7.91µm and 53/70/88/105keV. These data can be used for training ink detection models, or for investigating the differences between scans at different resolutions and energies.       |
| campfire.zip 338MB | X-ray scans and images of the Campfire Scroll (used in tutorials).  |
