About
AstroVision is a first-of-a-kind, large-scale dataset of real small body images from both legacy and ongoing deep space missions, which currently features 115,970 densely annotated, real images of sixteen small bodies from eight missions. AstroVision was developed to facilitate the study of computer vision and deep learning for autonomous navigation in the vicinity of a small body, with speicial emphasis on training and evaluation of deep learning-based keypoint detection… See the full description on the dataset page: https://huggingface.co/datasets/travisdriver/astrovision-data.AstroM3Dataset
AstroM3Dataset
Description
AstroM3Dataset is a time-series astronomy dataset containing photometry, spectra, and metadata features for variable stars.
The dataset was constructed by cross-matching publicly available astronomical datasets,
primarily from the ASAS-SN (Shappee et al. 2014) variable star catalog (Jayasinghe et al. 2019)
and LAMOST spectroscopic survey (Cui et al. 2012), along with data from
WISE (Wright et al. 2010), GALEX (Morrissey et al. 2007), 2MASS… See the full description on the dataset page: https://huggingface.co/datasets/AstroMLCore/AstroM3Dataset.minty-astro-ph
