- Material: ??
- Pattern: One styrene-vapour (~20 nm speckles), one water-vapour (larger)
- SEM: Magellan\Quanta? Or Magellan for both to keep consistent?
- Two successive images, calculate error values in Exx, Eyy
- Take image of SEM calibration grid to asses spatial distortion
- Magnification -> what mag is best for a given pattern size, is magnification value accurate, does it change in different sessions, is there any spatial distortion
- Current\Dwell -> what parameters are best to minimise error and distortion
- Focus -> Go in\out of focus to asses error
- Brightness\Contrast -> is there an optimal histogram to achieve least noise
- Stitching -> how does stitching affect the error values
