Principle of final alignment adjustment of the streak slit along the microscope image obtained on Omega shots: (a) initial position of the streak slit, (b) streak slit moved horizontally to the left side, and (c) final vertical adjustment by moving the streak slit vertically. (Dimensions of the pattern are given in the object plane).
