 The consistency check for beam size calculation in Q7 shows:\\

-Start beam emittance= XX * AX= 0.2 π mm mrad, so the emittance grows from the start to the focal point.\\
+Start beam emittance= XX · AX= 0.2 π mm mrad, so the emittance grows from the start to the focal point.\\
-This emittance grow is possibly due to the optics aberrations. 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.]\\
