macro/param/*.root for Fwd EMC
type: item
description: Dear collegues, I have seen that some correction files under /macro/param/ electron_en_th_corr_TGeant3.root electron_en_th_corr_TGeant4.root and also exist for gamma and other. Are they related shashlyk FWD EMC? What stands for? Best wishes, Mery Christmas! Donghee

description: Hi Donghee, those files electron_en_th_corr_TGeant3.root electron_en_th_corr_TGeant4.root containes energy-position corrections for both target EMC and shashlyk forward EMC. But the files existing in svn, i.e. gamma_en_th_corr_TGeant3.root, electron_en_th_corr_TGeant3.root contain correction only for gamma and version for electron is simple copy of version for gamma. See http://forum.gsi.de/index.php?t=tree&th=2758&start=0&rid=78& amp;S=021fd175a9f9c53e803355e1c5067751 and http://forum.gsi.de/index.php?t=tree&th=2758&start=0&rid=78& amp;S=021fd175a9f9c53e803355e1c5067751#page_top for details how to use them (particularly in macro /macro/emc/dedicated/emc_complete_corr.C). Recently I added new class EmcCorr/PndEmcClusterCalibrator.cxx to use correction in parralel with parametrized corrections and some related macros to calculate them in /macro/emc/dedicated/EnergyPosCorrection but this work is still in progress.
