{"url":"/dataset/lco-cr-dataset","name":"LCO CR Dataset","full_name":"Las Cumbres Observatory Cosmic Ray Dataset","description_markdown":"Cosmic rays in the 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 dataset of its kind. It consists of over 4,500 scientific images 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. \r\n\r\nUsage: https://github.com/cy-xu/cosmic-conn\r\n\r\nFor technical questions regarding the Cosmic-CoNN LCO CR dataset, please contact cxu@ucsb.edu.\r\n\r\n### Licensing of images and data\r\nAll images and data derived from observations made at LCO facilities are made available for scientific or educational use, subject to the Creative Commons license BY-CC 2.0 and in the case of science data, subject to an additional proprietary period. This allows for all LCO data and images, which are not subject to a proprietary restriction, to be freely shared and redistributed on the condition that an appropriate attribution is made.\r\n\r\nAny use of LCO images and data not for scientific or educational purposes, e.g. for commercial purposes, is not permitted unless through an explicit arrangement.
