   2. Alignment
      • Alex suggested to iterate MilleKs to check whether the results really converge or not.
      • Also, we should confirm that MilleKs can adjust multiple parameters simultaneously.
      • Beni suggested to align (rotate) FDCs on a chamber-by-chamber basis (4 FDC chambers). Currently, alignment is carried out on a plane-by-plane basis (24 FDC planes). This may help to avoid to be stuck in local minimum.
