{"url":"/dataset/plasticc","name":"PLAsTiCC","full_name":"Photometric LSST Astronomical Time-Series Classification Challenge","description_markdown":"The PLAsTiCC dataset is a collection of simulated light curves from the Photometric LSST Astronomical Time-Series Classification Challenge. This diverse dataset\r\ncontains 14 types of astronomical time-varying objects, simulated using the expected instrument characteristics and survey strategy of the upcoming Legacy Survey of Space and Time\r\n[LSST 79] conducted at the Vera C. Rubin Observatory. \r\n\r\nThe dataset includes two overall categories of time-series objects: transients, which are short-lived events such as supernovae, and variable sources, which are objects with fluctuating brightness such as pulsating stars. Specifically, the dataset includes the following transients: type Ia supernovae (SNIa), SNIax, SNIa-91bg, SNIbc, SNII, superluminous supernovae (SLSN), tidal disruption events (TDE), and single lens microlensing events (µLens-Single); and the following variable objects: active galactic nuclei (AGN), Mira variables, eclipsing binary systems (EB), and RR Lyrae (RRL).\r\n\r\nThe dataset contains a collection of 3,492,890 time-series, providing in each case several fields: time of observation, flux, flux error, and filter in which the flux is measured. Observations in 6 filters are included (u,g,r,i,z,Y). In addition, each time series is associated with a class representing the type of object, and a redshift for that object.","description_withheld":null,"homepage":"https://users.flatironinstitute.org/~polymathic/data/MultimodalUniverse/v1/plasticc/","introduced_date":"2018-09-28","introduced_date_note":null,"introduced_by":{"paper":"/paper/the-photometric-lsst-astronomical-time-series","title":"The Photometric LSST Astronomical Time-series Classification Challenge (PLAsTiCC): Data set","first_author":null,"url":null},"license":{"name":"CC BY 4.0 License","url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"modalities":[{"name":"Time series","url":"/datasets/modality/time-series"}],"tasks":[{"name":"Time Series Classification","url":"/task/time-series-classification","datasets_with_task":"/datasets/task/time-series-classification"},{"name":"Astronomy","url":"/task/astronomy","datasets_with_task":"/datasets/task/astronomy"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["PLAsTiCC"],"data_loaders":[],"num_papers_in_archive":10,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
