Scanback:

   - Only 2 tracks (id 4 and 8) remain after plate 50
   - They are followed up to the end of the brick

Chi2 VS grains

Using the extrapolation of the 2 last BT found in plate 1, the vertex is located outside the brick in the TT wall with an IP of 14.4 microns at a distance of 3.3 cm of the plate 1. This is confirmed by the TT signal osberved in second TT wall and not in the first:

TT signal

Volume Scan:

   - No "standard" volume can be performed as no stopping points are found.
   - In order to see if additionnal tracks or showers can be attached to the vertex, we decide to do volume scan from plate 1 to 10.
   - Scanning is almost done.... but not yet analyzed
