Hi
I found some inconsistencies with the geometry information corresponding the
the straw tubes in the FS.
All FS straw tubes (PndFtsTube Objects ) are stored in a TClonesArray
and indexed vis the TubeID.

A dump of values shows that for the 2nd layer the tube position is wrong ( notably wrong Z ) :


-I- PndFtsClusterFinder:: ReadFtsHits()
-I- Digits Data: fHits[0] is branchID 5 name# FTSHit entries# 49
-I- PndFtsClusterFinder ChamberID# 1 LayerID# 1 TubeID# 51
-I- PndFtsClusterFinder Tube position X: 13.635 Y:0 Z:294.895 R_meas: 0.208595
-I- PndFtsClusterFinder wire direction
wx# 0 wy# 1 wz# 0
0
-I- PndFtsClusterFinder ChamberID# 1 LayerID# 2 TubeID# 192
-I- PndFtsClusterFinder Tube position X: -95.95 Y:0 Z:423.765 R_meas: 0.330289
-I- PndFtsClusterFinder wire direction
wx# 0 wy# 1 wz# 0

The Z position should be instead Z=295.75 ?

Any idea ?
