Declare a new Gaudi property.

Parameters

Declare a new Gaudi property.

Parameters

◆ execute()

Create the context object

Random engine to smear the segment parameters

Loop over the segment container

Fetch the measurements

We add two pseudo measurements above & beneath the segment to stabilize the fit

Global chi2 fitter runs only with at least 5 measurements

Fetch a smeared segment position & direction

Construct the reference surface before the first measurement

Reference position of the surface.

Plane surface

Fetch the measurements from the track state

Direction is always expressed in global frame -> transform to local

Express the parameters at the reference surface of the original segment

Straight line extension to plane

Seed paramters
