Results from Test 2. Upper panel: input substructure cumulative mass function (green line) compared to ASOHF results with n_ℓ = 1 (red) and n_ℓ = 2 (dark red). The vertical lines mark the completeness limit, this time at 99%, of the catalogue produced by ASOHF. Bottom panel: fraction of substructures with input mass higher than M detected by ASOHF, with the same colour codes as above.
