Local and global software compensation approaches: application to test beam data

In this note, we present improved results for the energy reconstruction of pion events in the CALICE AHCAL, using local and global software compensation. Both techniques are applied to the same event samples selected from the CERN 2007 test beam period, covering an energy range from 10 GeV to 80 GeV. The run and event selection procedures have been improved and are identical for both methods. Both local and global software compensation techniques show similar improvement in single particle energy resolution ranging from 12% to 25%, depending on particle energy.
