Following up from the previous post:

We want to know what's going with a strange dip in the reconstructed recoil track pT spectrum (located in the trigger pT range). There were no leads in the various track quantities we cut on (see the above link), so we opted to check the quantities we use to match reconstructed tracks to generated particles.

Just like before, the plots below show 'IdTruth' (the index of the generated particle with the most number of TPC hits in common with the reconstructed track in question) and 'QaTruth' (the number of TPC hits in common with a given generated particle presented as a percent) for 2 different ranges of pTmc, all pTmc and pTmc > 8 GeV/c (roughly the trigger range).

Again, the ratios are flat... So nothing to go off here...
