Model inputs varied in the Monte Carlo ensembles, grouped by the physical role in the EFR framework.

Group Parameters varied Notes / description
Geometry / spatial scales h0, sf, ratio Eruption onset height (h0), footpoint separation (sf), and aspect ratio (ratio) controlling flux-rope geometry and expansion scaling.
Poloidal-flux injection profile τ1, τ2, t1, t2, t3, q1 Rise/decay timescales (τ1, τ2), timing markers (t1, t2, t3), and injection amplitude (q1) defining the prescribed dΦp/dt driver.
Magnetic-field initialization Bp, Bt Initial poloidal and toroidal field strengths setting the starting magnetic content of the rope.
Plasma density / mass loading ncavity0, δ Initial cavity number density (ncavity, 0) and prominence fall-off / residual factor (δ) controlling internal mass loading and its evolution.
Solar-wind background and coupling vsw0, nsw0, Cd Upstream solar-wind speed and density, and the drag coefficient controlling momentum exchange during propagation.
