The bottom panel shows 6 of the 53 groups found by our algorithm. The color-coded positions of the spectra for this raster have been overlaid onto the SJI. The Mg II k profiles emerging from each location are assigned to one of the 53 groups based on which group they are most similar to. This analysis has been applied to multiple flares leading to interesting discoveries that indicate typical emissions and shared chromospheric physics for all flares.
