Data have been reconstructedand analyzed offline with two reconstruction methods: the charge centroid and the micro-Time-Projection-Chamber exploiting the charge and the time measurement respectively. A combinationof the two reconstruction methods is capable to guarantee a spatial resolution better than 150{\\mu}min magnetic field up to a 1 T.","authors_text":"A. Amoroso, A. Bortone, A.
