Jaccard distance between AIA and HMI masks as a function of AIA threshold. (a) AIA bright pixel masks and HMI moderate field (55 G > B > 475 G) masks. (b) AIA dark pixel masks and HMI strong field (B > 1365 G) masks. The yellow lines show the value of the Jaccard distance, while the blue and orange lines show the contributions of false negatives (DFN) and false positives (DFP).
