Analysis of the 1997 test beam laser data of the Tilecal exetnded barrel module 0

This note presents the analysis of the laser data taken during the tesbema of october 1997. The test beam configuration of th elaser will be introduced. the stability of the read-out electronics of the two extended barrel module0, determined by th erelative gains will be shown. The number of photoelectroncs will be calculated and correlations between the CS and the laser system will be shown as well.
