Analogue, Digital and Semi-Digital Energy Reconstruction in the CALICE AHCAL

In this note, different energy reconstruction methods for the Analogue Hadronic Calorimeter (AHCAL) are compared. These methods were developed for the analogue, digital and semi-digital CALICE Hadronic Calorimeter physics prototypes and were used in analyses of data taken at various test beams. The analogue data can also provide digital information, thus the advantages and disadvantages of different energy reconstruction procedures can be studied in the same data sample. In this work this comparison is done by applying these procedures to AHCAL pion test beam data collected with the 1 m$^3$ physics prototype in 2007 at CERN. The results are compared to a GEANT4 based simulation.
