Description

Currently, the calibration within leginon is not good enough but can be done with AutoCTF from Thermo Fisher. This feature allows those results to be enterred directly.

Beam tilt unit is radians.
Beam-image shift (Known as image shift in leginon calibration) is in meters.
Read the beam tilt, stig, and defocus values from Scope EM node by refreshing its displayed values after AutoCTF make coma, stig and defocus correction.

BT_X(IS_X,0) = x axis beam-tilt required to bring image shift of (X, 0)
BT_Y(IS_X,0) = y axis beam-tilt required to bring image shift of (X, 0)
slope(BT_X(IS_X,0)) = the slope of a line fitting a series of BT_X at different (IS_X,0)

image-shift coma = [[ -slope(BT_X(IS_X,0)), -slope(BT_X(0, IS_Y)],
                      -slope(BT_Y(IS_X,0)), -slope(BT_Y(0,IS_Y)]]

image-shift stig = [[ -slope(Stig_X(IS_X,0)), -slope(Stig_X(0, IS_Y)],
                      -slope(Stig_Y(IS_X,0)), -slope(Stig_Y(0,IS_Y)]]

image-shift defocus = [[ -slope(Defocus(IS_X,0)), -slope(Defocus(0, IS_Y)],
                         1,                               1             ]]
