| 4 | 3 | Amber Herold | The BeamFixer acquires 3x3 images at the requested beam shift step size centered around |
| 5 | 1 | Amber Herold | the current value to find the best beam shift and then update the value to Presets Manager. A |
| 6 | list of presets that the update is to be applied is entered in the settings and the first |
||
| 7 | preset in the list is used for the best beam shift determination. The beam shift step size is |
||
| 8 | relative to that of the imaging area of the first preset, too. |

| 41 | |
||
| 42 | The type of calibration movement that is used to navigate to the target. In general, modeled stage position or stage position should be used. |

| 50 | * Presets Order List |
||
| 51 | 3 | Amber Herold | |
| 52 | The first preset is used for best shift determination. The beam shift of all presets in the list will be updated with the best value determined in this process. In general, these are presets at the same and the highest magnification used in final acquisition and fine autofocusing. The preset with smallest beam foot print would be the best as the best shift determining preset. |

||
| 59 | 3 | Amber Herold | |
| 60 | Used mainly in testing and/or when the best-shift-determining preset is of large dimension so that it is slow to acquire. |
