Detailed Description

Measurement at point.

User supplied measurement at point on (initial) trajectory.

Must have measurement (1D - 5D). May have:

Additional local parameters (with derivatives). Fitted together with track parameters.
Additional global parameters (with labels and derivatives). Not fitted, only passed on to (binary) file for fitting with Millepede-II.
