The data set consists of 50 confined ($62\\,\\%$) and eruptive ($38\\,\\%$) flares that occurred from June 2000 to June 2015. The flares are selected homogeneously over the H$\\alpha$ and $\\textit{GOES}$ (Geostationary Operational Environmental Satellite) classes, with an emphasis on including powerful confined flares and weak eruptive flares.
