Results for the 600 s for heating pulse simulations (Sect. 4.1) when run with the JB19 formulation of the TRAC method (upper six panels) and a fixed percentage cutoff temperature (lower six panels). The panels show the coronal averaged temperature and density, as functions of time, the time evolution of the cutoff temperature (T_c), the normalised differences between the coronal quantities, and the radiative losses integrated across the TRAC region (ℛ_TRAC) and total over half of the loop (ℛ_TOTAL). The lines are colour coded in a way that reflects the conduction method used with dashed blue (solid red) representing the TRAC (SH) solution. Each set of six panels (upper and lower) can be compared with Fig. 1, which shows the results when TRAC is run with the cutoff temperature limiter. Starting from the top left, the corresponding panels in Fig. 1 are a, b, g, c, d and i, respectively.
