I think this is the paper: https://arxiv.org/abs/2105.01056 . It's all open sourced, and Python. From the paper, previously you needed a sequence of images from a single night to generate a "tracklet," which lets you estimate a guess of the orbit of the asteroid. The guess can be compared with images from other nights, to confirm the existence and orbit of the asteroids. Without the tracklet, the asteroid could be heading in any direction, meaning that the set of possible orbits is huge, and there would be many many possible matches to other images. The key insight of THOR (their algorithm)…
