Draft: Configuration for HLT2 PrVeloUT
There's some physics interest in HLT2 Upstream tracks. The current default config of the PrVeloUT aims at reconstructing higher momentum tracklets that are really part of a Long track (i.e. a HLT1 scenario). Given that PrVeloUT does not need to fulfill the HLT1 purpose anymore, let's use it for actually finding a decent amount of Upstream-notLong tracks.
- timing-wise this slows down the PrVeloUT algo by a factor ~6 which is probably still negligible within the whole HLT2 seq, however, the Kalman Filter for upstream tracks gets a factor 4 slower which might not be negligible
Closes #640
