The Alignment and Calibration of the Belle-II Central Drift Chamber with first cosmic data

This document reports on one of the alignment and calibration procedures of the Belle-II Central Drift Chamber. The study is performed on cosmic data collected with the CDC. General Broken Lines algorithm and Millepede II are used as the main instruments in this procedure. ROOT and Shell scripts have been implemented for experimental data processing and analysis of the distributions. Corrections of Central Drift Chamber parameters were found. Distributions of resolution for each layer are fitted with theoretical function. The best resolution is about 120 µm for outer layers and 140 µm for inner layers.
