Notes. The first column labels the GOES class that the flares belong to. The second column signifies the total number of flares in the corresponding class. The third and fourth columns depict the number of eruptive and confined flares, while column 5 and 6 show the corresponding percentage of eruptive and confined flares with regards to the overall number of flares in that class. The eruptivity data for the flares ≥C5.0 are from Li et al. (2021).
