Fitting a trajectory at various points in line

I think I see now.I should use MARK instead of MONI as the BPM point, and set fitpoint=1.
Is that right ?

I am trying to fit a trajectory using as optimization_variables non conventional elements, the transverse displacements
of a linac. I am doing this to see whether such displacements can account for the measured trajectory at the BPMs. The way I understand it, the optimization procedure only allows me to fit the final values of a trajectory and not also intermediate values. Is there any way to do this ?
Thanks, Max

Max,

Yes, that's correct. If you define your marker using a statement like
M1: MARK,FITPOINT=1
then you can use M1#<n>.Cx and M1#<n>.Cy to optimize the trajectory, where <n> is the occurrence number of the marker .
