MANY advantages!!
- Allows the inclusion of multiple scattering
- Allows the inclusion of energy loss
- Capable of handling non-uniformities in the magnetic field
- Fast and efficient
- Invloves the inversion of an nxn matrix where n is the number of parameters
- A global c2 fit (including multiple scattering) involves the inversion of an NxN matrix where N is the number of measurements
- Don’t need to redo the fitting when a measurement (detector) is removed!!
- Get the detector calibrations for free!
- Can easily determine outliers (cross talk, noise, hits belonging to other tracks)
- Big gain in efficiency!!
