fit DEM curves as shown in the top panel of Figure \[fig:aia\_dem\].[]{data-label="fig:temp_A"}](fig10.eps){width="50.00000%"}

To separate out hot plasma components from the background at foot-points and along the loop, we fitted the DEM curves with 4 Gaussian functions and polynomial of degree 2, similar to the approach employed by @2011ApJ...732...81A. Chosen function best represents the DEM curves for the desired purpose. These fitted profiles also provide the temperature of different plasma components. The four Gaussian components represent cool ($\approx 10^{5.8}-10^6$ K), warm ($\approx 10^{6.2}-10^{6.3}$ K), intermediate ($\approx 10^{6.2}-10^{6.7}$ K), and hot ($\approx 10^{6.7}-10^{7.2}$ K) temperature plasma components. These Gaussian functions representing different temperature components are over-plotted with different colors in Figure \[fig:aia\_dem\]. We use red and green color to represent the cool and warm background plasma, respectively. The dark blue color represents newly emerged hot plasmas due to the ARTBs. The intermediate temperature plasma component was added to obtain the best fit for the DEM curves and are represented with blue color. Although this component is added only to full fill the best fit requirement, it can be interpreted as the appearance of intermediate hot plasma component. This plasma component initially appears with hot plasma component and later merges with warm background
