Electron temperature T_max and density n_max at the loop center (s = L_c + L/2) at the time of the temperature peak after the impulsive heating. Prior to the impulsive heating, the initial values T_ini and n_ini at the loop center are provided for the loops in equilibrium. Results for groups I (left column) and III (right column) are shown for initial cool (upper row) and hot loops (lower row). The X-axis is the changing parameter associated with each group (L or A_max). Model numbers given in Tables 1 and 2 (i.e., m₁ to m₃₅) are displayed on top of their respective data points (crosses). The horizontal black line delimits the 1 MK temperature, above which the heating is likely to contribute to coronal heating.
