v1.2.2 - Recon Pass 2 Release

This release will be used to run reconstruction pass 2. It adds several features that will enhance the 2018 LDMX whitepaper studies:

What's New

• Generic noise model that can be used by any subdetector (#414)

v3 Recon Release

This release marks the first stable version of the reconstruction that will be used to process all v3 samples. The resulting recon files will be used for studies included in the 2017 LDMX whitepaper.

This is the first iteration of the recon. Several other changes are likely in the coming weeks.

What's New

• Regeneration of events using particles that cross a scoring plane of interest (#346)
• Pre-processor macro is now used to define a sim plugin (#261)

• BDT is retrained and improved (#391)
• Add ability to skim a file based on whether it passes the Ecal BDT veto (#398)
• PN re-weighting is implemented (#294)

Bug Fixes

• Fixes to SimpleProcessFilter which keep it from filtering out events where a reaction of interest has already occurred (#352)
• Save the generator particles even if the are instantiated within a volume where trajectory saving is turned off by default (#346)
• Plugin messengers missing method call to parent (#382)
• EcalDigiProducer was using the incorrect layer weight for the last Ecal layer (#395)

v3 Production Release
