Petr - update on K->3pi. Based on the the track and hit visualisation it seems that the previously observed high efficiency for matching the mother kaon to the decay vertex in th inactive parts of the TPC is caused by traccker picking up additional hits which prolong the track beyond the decay vertex. The KFPF is then unable to match the track when trying to project it forward hence the decrease in the efficiency.

GMT- David has changed the order of commands in BFC which likely removed the previously seen problem.

Robert - The comparisons between his and DIma's embedding shows same results. Now the question is if there is a possible difference in real data. Robert was ask to run his code on the data that Dima previously reprocessed for his study.
