class AliTPCParamSR: public AliTPCParam

constructor set the default parameters

destructor destroy some dynmicaly alocated variables

set default TPC param

calculate bin response as function of the input position -x
return number of valid response bin

we suppose that coordinate is expressed in float digits
 it's mean coordinate system 8
xyz[0] - float padrow xyz[1] is float pad  (center pad is number 0) and xyz[2] is float time bin
xyz[3] - electron time in float time bin format

 transformate point to digit coordinate

transformate point to rotated coordinate

we suppose that

transform relative coordinates to absolute

transform global position to the position relative to the sector padrow
if option=0  X calculate absolute            calculate sector
if option=1  X           absolute            use input sector
if option=2  X           relative to pad row calculate sector
if option=3  X           relative            use input sector
!!!!!!!!! WE start to calculate rows from row = 0

return cluster sigma2 (x,y) for particle at position x
 in this case x coordinata is in drift direction
and y in pad row direction
we suppose that input coordinate system is digit system

calculate angle of track to padrow at given position
 for given magnetic field and momentum of the particle

 Stream an object of class AliTPC.

calculate bin response as function of the input position -x
return number of valid response bin

we suppose that coordinate is expressed in float digits
 it's mean coordinate system 8
xyz[0] - electron position w.r.t. pad center, normalized to pad length,
xyz[1] is float pad  (center pad is number 0) and xyz[2] is float time bin
xyz[3] - electron time in float time bin format
