Lift height-dependent reconstruction for volume MFM data: (a) evolution of estimated optimal regularisation parameter σ; (b) TTF width measured using formula (21) for σ estimated at each lift height and three fixed values within the range of more or less constant optimal σ; (c) evolution of TTF with lift height calculated from volume MFM data with slices at selected heights (colour ranges are adapted to full range of each individual slice).
