Detailed Description

User supplied measurement at point on (initial) trajectory.

Must have measurement. May have:

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

Constructor & Destructor Documentation

__init__()

def gblpy.gblfit.GblMeasurement.__init__	(		self,
