Auto CTF is not working properly
These are possible resolutions for the issue:
- Restore default settings
These are possible causes for the issue:
- Sherpa setting not correct
Auto stigmatism and auto coma of Auto CTF in the Sherpa is not working properly. Issue fixed by restore default settings.
Notes: As this tool has Cs image corrector, so the comma correct function is not available. The coma correction has to be done in the Cs image corrector software. For the non-Cs image corrected systems, Sherpa Auto CTF uses the beam tilt to correct coma .
