This frame allows to define the nanoprobe at the specimen entrance. Aberrations up to order 8 can be set either using sliders or text fields. The coherence tab allows to set the energy spread of the electrons as well as the lens and current stabilities.

This tab contains two sets of controls for adjusting the aperture diameter, the chromatic aberrion (W₀₀), the virtual source size and the thermal magnetic noise. The defocus value can be adjusted using the ↑, ↓ keyboard keys (with the mouse on the CTF drawing).
