===== Studies =====

==== Analysis steps ====

   * Starting with regas studies (July 6 after lunch) to compute S-T relations
   * Running 'plain' Analizer.
   * Clean Fit should be defined with **1 hit on new chamber** on plan0 [chs 1-3 tdc disconnected]

==== How to compute the T0s ====

   * The TB values where computed by Till [Jul 2010]
   * Code (from till): T0dch_new [compile with proper Makefile, after changing hardcoded file names]
   * checked that the central values are nearly stable [To be checked in detail]

=== To Do ===

  - Check T0
  - Develop a clever it
