Vertex point (-VP) vs magnet center (-C)

[libov]

Dear Michael,

I'm using floor_coordinates command to get the absolute coordinates of the magnets.

For dipoles, one can get three points: the vertex point (-VP), the magnet center (-C) and the exit.

My question is: how is the center defined? Is it the center of the line connecting entrance and exit?
That is, point D on the attached drawing?

(one could also in principle define it in a different way, e.g. the symmetry point on the trajectory, i.e. point C)

Thanks!

forgot the drawing...

Slava,

The center is the average of the input and output floor coordinates, which corresponds to the point D on your drawing. I'll add a note to the manual to clarify this.
