 This emittance grow is possibly due to the optics aberrations. That is because the input COSY file does a 4th-order-calculation. Also the measured points don't fit the parabola ideally, i.e. the optics is non-linear.\\

 Created loop for target position. Observed piece-wise curve for resolution vs target offset (meters) (see figure below) in case of 4th order calculation. If order reduced to the 1st, than curve is smooth, but maximum resolution is shifted.
