Preliminary results from hadron shower data with the CALICE tile AHCAL prototype

For the purposes of the work contained in this note a set of pion data has been analyzed. The focus of the analysis is to the operation of the analogue hadronic test-beam calorimeter (AHCAL), though the other two detectors are needed for data selection and event topology selection, and had to be calibrated and understood as well. The presented analysis is related to classical shower parameter studies as the linearity of the calorimeter response, the energy resolution and the energy dependence of the shower profiles. These basic understanding is mandatory before going into the next step of shower decomposition, which is the main goal of the hadronic shower analysis.
