Fake calibrations for Leginon simulator
Read the instruction for real Calibration Application on details like how to load application, entering the values which I will not repeat here.
Create presets:
- A highly binned camera configuration such as 512 binned by 8 is sufficient.
- As a short cut you can use the same magnification for all presets. If using more magnifications, you will have to calibrate them, too.
- Always send the preset with the magnification you want to "calibrate" first "to Scope".
Pixel Size Calibration:
- Enter Calibration for 50000x as 2e-10 m/pixel
- Extrapolate the pixel size to all other simulated magnifications
Matrix Calibration:
-
Use Edit Calibration Tool, you can enter directly the calibration matrix. For example, my standard matrix for 50000x looks like this: 2e-10 0 0 2e-10
You will want to scale it down for lower magnification. For example, the one for 5000x should have 10 x in values at each matrix element.
Beam Tilt related Calibration:
- Just go through the defocus calibration as if it is a real scope/camera is good enough.
Dose (Camera Sensitivity) Calibration:
- Enter Camera Sensitivity of some value such as 5 counts/electron.
