Hi Everybody,
I found some cases where the helix prefit is still better than
the kalman fit. Again I used the same parameters but different
particles.
Kaons (efficiency loss, background):
Protons (efficiency loss, worse result):
The flags for the failed Kalman fits are in both cases:
90%: -1
10%: -2
@Lia: thank you for the short tutorial
greetings,
David
