Timing per track
Timing measured as difference between the main and parasitic PCs. With
main running
L2 XFT algorithims and parasitic without.
CPU timing (in mircoseconds) versus number of attempted
reconstructions, any two triggers in green,
CMUP in blue, CMX in red, CEM in black. CMX uses valid track algorithim,
CMUP and CEM use best
track algorithim.

CPU timing (in microseconds) versus number of attempted reconstructions
fitted for all events where L2 XFT
stereo reconstruction was attempted.
