Figure 5

Instrumentation errors and their effect on TTF: (a) detail of a MFM phase image with magnetisation switches and other line artefacts; (b) the same image with switches corrected; (c) strike-through artefact caused by scan line errors; (d) strike-through artefact removed by utilisation of uncorrelated images; (e) stripe artefacts caused by lift height variation; (f) single-pixel spike artefact caused by correlated point noise. The colour scales in parts (c–f) illustrating individual artefacts are adapted to always match the full data range.
