The purpose of this document is to collect all the data for the Glast LAT Tracker (TKR) Tower End Item Data Package (EIDP), in compliance with LAT-TD-04350 and PRC_Pi_QC_005. This document is compiled and reviewed within the Tracker subsystem prior to shipment of Tower A from INFN to SLAC. The contents of this document have been coordinated between LAT Integration, Test, and Calibration (IT&C), LAT Systems Engineering (SE), LAT Quality Assurance (QA), and the TKR subsystem.
