Top panel: six SSHEs tracked by the method over their lifetime in the LRM. The data points show the value of the Joule heating at the location (cell) of maximum dissipation of the SSHEs while they are above the background, which in this case is chosen as 10¹⁷ erg s^-1. The data points connected by a solid line represent the SSHEs considered in the statistics while those connected by a dashed line represent the disregarded SSHEs. Bottom panel: Number of SSHEs with a clear rising and decaying phase inside each energy decade ranging from 1 × 10¹⁹ to 1 × 10²⁷ erg for two different backgrounds 10¹⁸ erg s^-1 (dashed line) and 10¹⁷ erg s^-1 (solid line) for the LRM.
