Hi,
I checked the differences for momentum recosntructions, using 10k muons at 0.5 GeV/c in the barrel.

This the comparison w/ (blue) and w/o (red) backward propagation to the IP:

index.php?t=getfile&id=7305&private=0

This the comparison with the standard initial plabe (blue) and with the perpendicular plane (red)

index.php?t=getfile&id=7306&private=0

It appears evident that the orientation of the plane does not affect teh results, while w/o back propagation the counts are less. The latter point is not well understood by me.
