Dear all,
now a Kalman Filter is also provided with lhetrack code, so for TPC+MVD and STT+MVD.

Let me show the difference between lhetrack fit for muons at 1GeV and genfit refit.

TPC+MVD:

index.php?t=getfile&id=4764&private=0

STT+MVD:

index.php?t=getfile&id=4765&private=0

...
...
in practice there are no strong differences.

You can find some macros on how to run it, after the standard sim/digi/recom in tutorials/lhetrack:

* run_kalman_tpc.C
* run_kalman_stt.C
* plot_kalman_tpc.C
* plot_kalman_stt.C


At the moment, in the code you can see that three iterations are performed and even smoothing:

Toggle Spoiler


You can switch ON/OFF or play with these parameters.

Probably fixes will be needed, but at least it seems to work.
