Notes. These are computed over the white (enclosing the point “P” of panel A in Fig. 4), blue (TELs, marked “L”) and black (loops at the bottom, marked “D”) boxes marked in Fig. 9. Similar computations are done for “P2” region, which undergoes concurrent intensity enhancements during E2 (as shown in Fig. 5). The density estimates consider background/ foreground emission over the region marked “B” in the Fig. 9. No background/foreground emission treatment has been done for the temperature estimates.
