Cosmic-CoNN Las Cumbres Observatory CR dataset

Cosmic rays in the Las Cumbres Observatory (LCO) CR dataset are labeled accurately and consistently across many diverse observations from various instruments. To the best of our knowledge, this is the largest cosmic ray dataset that identifies CRs in science images across various ground-based instruments. It consists of over 4,500 observations from Las Cumbres Observatory global telescope network's 23 instruments. Each sample in our dataset is a multi-extension FITS file, including three images, three corresponding CR masks, and three ignore masks.
