[Rich] Info Trajectory used in the RICH cluster position analysis

[Giovanni Angelini]

Dear All,

The info  requested during today’s meeting are here summarized:


In the analysis I have shown in today’s meeting, the track trajectory is defined as the vector connecting position of REC::Traj on layer: 36 with layer: 42  (the last two of the DC)  This vector has been intersected on the PMTs using the RICHG4Factory and compared with the position of the cluster.

For the PCAL the REC::Traj position of layer 47 (front face of  PCAL) is compared with the closest cluster from REC::Calorimeter


The table with all the Traj planes is the following:
detId	Description
0 	HTCC spherical surface
1-6 	FMT planes
12/18/24/30/36/42 	last DC wire plane in each superlayer
43 	LTCC plane
44/45/46 	FTOF 2/1B/1A front face
47/48 	PCAL/EC front face


Best,

Giovanni
