Effect of applying boundary conditions on the fit parameters of the Gaussian decomposition for the SOL2022-05-04 flare. Panel (a) shows the resulting fit when the boundary conditions shown in Table 2 are applied. Panel (b) shows the resulting fit when no boundary conditions are applied. Both cases give a good fit to the data, however, the unconstrained fit (Fig. 10b) fits long period Gaussians with small amplitude peaks, for instance, at ∼15:17:08. This fit is interesting from a physics point of view, however in this work we wish to derive timing information regarding the global peak trend – therefore a constrained fit is preferable.
