ebtelplusplus input parameters related to the physics of the simulation

Parameters:

saturation_limit (float) – Flux limiter constant. See Eq. 21 of Klimchuk et al. [KPC08]
force_single_fluid (bool) – If true, electron and ion populations forced into equilibrium.
c1_conduction (float) – Nominal value of \(c_1\) during the conductive cooling phase See Appendix A of Barnes et al. [BCB16].
c1_radiation (float) – Nominal value of \(c_1\) during radiative phase. See Eq. 16 of Cargill et al. [CBK12b].
use_c1_gravity_correction (bool) – Use correction in Eq. 12 of Cargill et al. [CBK12b].
use_c1_radiation_correction (bool) – Use correction in Eq. 16 of Cargill et al. [CBK12b].
surface_gravity (float) – Surface gravity in units of solar surface gravity. Should be set to 1.0 unless using for extra-solar cases.
helium_to_hydrogren_ratio (float) – Ratio of helium to hydrogen abundance; used in correction to ion mass and ion equation of state.
radiative_loss (str) – The kind of radiative loss function to use. Must be either “power_law” (to use radiative losses of Klimchuk et al. [KPC08], “coronal” (to use radiative losses computed with coronal abundances), “photospheric” (to use radiative losses computed with photospheric abundances), or “variable” (to vary the radiative loss function from coronal to photospheric as a function of density and temperature).
loop_length_ratio_tr_total (float) – Ratio between the length of the transition region and the total loop length. For a transition region of finite length, a typical value of 0.15 is used [CBKB22].
area_ratio_tr_corona (float) – Ratio between the cross-sectional area averaged over the transition region and averaged over the corona
area_ratio_0_corona (float) – Ratio between the cross-sectional area at the TR-corona boundary and the cross-sectional area averaged over the corona
