Pt resolution at low momentum Material thickness in unit of radiation lngth (%) From http://ilcphys.kek.jp/soft/geom2/geantino/ScanSummary.htm when multiple scattering dominates j4ldc would be about 15% better than gldapr08 at low momentum if fiited by TPC only Satellite fitting uses TPC+IT+VTX. Difference would be smaller
Control of TPC spatial resolution If $SATELLITESROOT/macros/S4Macros.C is used, TPC spatial resolution formula can be selected by S4TPC.SpatialResolution. = flat: constant in rphi and Z = experimental: formula implemented by Yamaguchi san = ILD or ILDAuto: ILD formulardescribed by the previous page. If ILD, q1 term is not scaled by Bfield. ILDAuto is default( Scaled by B) JSF parameter name and default values. They are defined in $SATELLITES/macros/S4Macros.C p1=S4TPC.Sig00 [ 0.005 ] p2=S4TPC.Sig0SinDep [0.090] q1=S4TPC.SigLDep [ 0.00053 ] r1=S4TPC.SigmaZ [0.040] S4TPCHit::SetXXXXX can be used to set parameters.
