“…4 and 5). In particular, as summarized in Table 2, we selected four of the simulations presented in Polito et al (2018) -with an initially empty cool loop (T ∼ 1 MK), of semi-length of 15 Mm, heated for 10 s by TC or NTE with 5/10/15 keV energy cutoff -, and five new simulations, all run on the same cool initial condition: (1) 10 s heating with TC and NTE with 10 keV cutoff (and total energy of 6 × 10 24 ergs, as in the previous runs), (2) intermittent heating (two 20 s heating episodes with 60 s pause in between) by NTE with 10 keV cutoff, (3) 30 s heating by NTE with 10 keV cutoff, (4) 30 s heating with TC and NTE with 10 keV cutoff, and total energy of 1.8×10 25 ergs, (5) 30 s heating by NTE with 15 keV cutoff, and total energy of 1.8 × 10 25 ergs. Figure 5 shows the predicted IRIS lightcurves (left column) for the nine selected RADYN simulations, synthesized by assuming an integration time (and cadence) of 4 s. A qualitative comparison of these synthetic lightcurves with the observed ones (shown in Fig.…”
