Basic description and units are included in the file _calibrations.xlsx_ - sheet _HELP_. Calibrations can be divided into groups based in its origin. -1. Nominal parameters which are given by STEM or detector manufacture and can be found in instructions or in their control software (beam energy, magnification levels, scanning unit matrices, detector pixel array size, pixel size). -2. Parameters which have to be measured (real beam semi-angle, beam diameter at 0 defocus, probe current, detector camera length, angular limitations caused by differential pumping aperture, scanning pixel size correction). -3. Computed parameter is then single pixel angle cover (dependent on used detector and its camera length). +1. **Nominal parameters** which are given by STEM or detector manufacture and can be found in instructions or in their control software (beam energy, magnification levels, scanning unit matrices, detector pixel array size, pixel size). +2. **Parameters which have to be measured** (real beam semi-angle, beam diameter at 0 defocus, probe current, detector camera length, angular limitations caused by differential pumping aperture, scanning pixel size correction). +3. **Computed parameter** is then single pixel angle cover (dependent on used detector and its camera length). ##### Probe semi-angle
