Hi All, Pelle, Omar, and Sho tracked down a bug in the detector geometry code that caused the positron-side sensors for layers 4-6 to be rotated incorrectly. This was causing us to miss a lot of positron tracks. This has been fixed (in lcsim) and Pelle added the necessary fixes to the compact.xmls for the HPS-EngRun2015-XXX-v1 set of detectors. If you are running tracking, you should switch to this set ASAP…if you are just looking at ECAL there should be no difference. We’ll deploy a jar with this fix to the counting house tonight so that monitoring will have it.
