δ̃G1 (0, 0.001, 0.01, 0.05, 0.10, 0.15, 0.20) 0.1 Σdust, large scale factor in gap 1
δ̃R1 0.5 1.0 0.05 0.75 Σdust, large scale factor in ring 1
δ̃G2 (0, 0.001, 0.01, 0.02, 0.03, 0.05, 0.1) 0.01 Σdust, large scale factor in gap 2
δ̃R2 2 5 0.5 4.5 Σdust, large scale factor in ring 2
δ̃out 1 3 0.5 1.5 Σdust, large scale factor in outer disk

Notes. For each variable parameter we explored a range of values between a minimum (Min) and maximum (Max) in regular steps (step). In the case of δ̃G1 and δ̃G2 we explored non-linearly spaced values, so we list them in parenthesis.
