Welcome to the Track Fitting task pages
Mission Statement: Track Parameters and Covariance Matrix for Online and Offline Applications
The Tracking task include the following activities: (Alignment should become a seperate activity):
- Track Event Model
- Track Fitting Algorithms
- Track Extrapolation
- Alignment Issues
- Composite Particle and Secondary Vertex Reconstruction
Approach:
- Activities include both online and offline applications
- Monitoring tools and quality checkers are implicitly included

In the tables below a summary of the activities is given. The idea is to expand for topics into a TWiki page of their own. So, please fell free to add to these pages.
1. Track Event Model
People:
- O.Callot, M.Cattaneo, J.A.Hernando, M.Merk, P.Koppenburg, G.Raven, E.Rodrigues
Requirements for the event model:
See the
Track Model Task Force pages, defining
tracks,
trajectories,
states and
measurements
Implementation of the Event Model:
2. Track Fitting Algorithms
Deliverables:
- Algorithms to estimate Track Parameters and Covariance for Charged Tracks
- Performance Estimation Tools using MC truth: "Checkers"
- Performance Estimation Tools using reco objects: "Monitors"
Inputs:
- Tracks Found by the Pattern Recognition algorithms in particular lists of assigned Velo, ST clusters and OT times
People:
- M.Benayoun, E.Bos, J.A.Hernando, M.Merk, M.Needham, C.Parkes, E.Rodrigues, H.Ruiz, J.v.Tilburg, Y. Xie, ...
Offline Kalman Track Fit:
- A list of topics relevant in the offline Kalman filter trackfit
_Note: for the new event model the code in Tr/TrXxxx becomes Tr/TrackXxxx_
Online Fit:
- A list of topics relevant for online parameter estimation
Performance Estimation Checkers:
In the
checkers the performance is evaluated by comparison with MC truth.
_Note: for the new event model the code in Tr/TrXxxx becomes Tr/TrackXxxx_
Performance Estimation Monitors:
In the
monitors the performance is evaluated using information in the data.
_Note: for the new event model the code in Tr/TrXxxx becomes Tr/TrackXxxx_

Deliverables:
- Track Extrapolation with full offline precision
- Fast online track extraplation
Inputs:
People: E. Bos, G.Corti, J.A.Hernando, J.v. Hunen, M.Merk, M.Needham, E. Rodrigues, ...
Extrapolator:
_Note: for the new event model the code in Tr/TrXxxx becomes Tr/TrackXxxx_
4. Alignment Issues
This should become a seperate project
Deliverables:
- Implementation of Misalignments in the MC
