+| `hd-epic/reference_frames/hdepic_refgeo-4b_2026-10-18.tar` | 2,847 files (22 MB), one per reference image of the HD-EPIC VQA questions (2,650 questions). Each holds the camera pose (Aria SLAM world), the depth of each token and each token's MEAN 3D point (12 x 12 tokens of a 384 px, 95-degree rectified frame). md5 `65381813477968f5deef7aebb04e88e1` |

+* **Who needs it:** only someone TESTING on HD-EPIC a model trained with `ref_pos=train`. Unpack it into
+  `<code>/results/cache/hdepic/` (it creates `refgeo-4b/`).
+* **One recording is empty:** the 51 references of P03-20240217-131219 hold NaN, because its released SLAM poses stop
+  at 22.8 of 54.6 minutes. None of its questions is in a scored set.
+* **Where it comes from:** HD-EPIC (Perrett et al., CVPR 2025). Cite it and follow its terms.
+* **The rest of the HD-EPIC test data is not public:** no HD-EPIC images, videos or tokens are in this share.
