Compressed track cluster compression: Alex Patton

Summary: New container storing clusters on tracks in TClonesArray, tested translation between standard and new formats. The aim is to reduce storage space.

Tony: clusters not on track are not used in the analysis

Tony/Joe: seeding only done upstream with full data

Tony: conversion time is negligible and supporting new->old translation is a good idea

Tony/Joe: redefining the cluster index is fine, which helps reduce storage space (as Alex suggested)

Joe/Alex: space saving statistics is still under study. Need thorough diagnosis before decision.

Jin/Tony: This would be useful for track refitting in reco-calibration stage and in some rare event analysis (like GSF refit for electron tracks). At the next stage of reco-analysis chain, majority track-based analysis would require new track object and container to dratmatically (1/100) reduction of data size for analysis.

Jin/Joe: offline discussion to ask Alex also to impliment the compact track object for HF analysis

HF Jet analysis objects： Jakub Kvapil

Jin: support storing in analysis repo, at least for now. It is likely variable addition/subtraction in near future, and we need work on schema

Cameron: if we run a central production, this should be evolved into a coresoftware module in the future

Derek: are calorimeter constituents stored too?

Jakub: calo info is PFlow based.

Tracklet analysis: let's validate with simulation, which partily driving this analysis file development.
