The 2018 Microlensing Data Challenge Dataset

A dataset consisting of timeseries photometry simulated to resemble the light curves that will be produced by the WFIRST Space Telescope (now the Nancy Grace Roman Space Telescope). This dataset formed the basis of a data challenge in 2018 where participants used the dataset to classify microlensing events, variable and constant stars, and to model the single- and binary lens microlensing events.
