class AliTPCParam: public AliDetectorParam

constructor sets the default parameters

destructor deletes some dynamicaly alocated variables

 calculates sector number (index[1], undefined on input)
 xyz intact

transformation from input coodination system to output coordination system

calculates pad row of point xyz - transformation to system 8 (digit system)

 set opening angles

return angle

return angle

return angle

return angle

give index of the given sector and pad row
no control if the sectors and rows  are reasonable !!!

return sector and padrow for given index
if index is reasonable returns true else return false

set default parameters

const static  Int_t kMaxRows=600;

sector default parameters

 update some calculated parameter which must be updated after changing "base"
 parameters
 for example we can change size of pads and according this recalculate number
 of pad rows, number of of pads in given row ....

 clean geo matrices

 read geo matrixes

 make local to tracking matrix

get information about object consistency

get the number of pad rows in low sector

get the number of pad rows in up sector

get the number of pad rows in up1 sector

get the number of pad rows in up2 sector

get the pad row (irow) radii

get the pad row (irow) radii

get the number of pads in row irow

get the number of pads in row irow

 Get Anode wire segment index IROC --> 4 segments in [0,3], 7 segments OROC[4,10]

 To  be speed-up using caching lookup table

 Get the number of pads in a given anode wire segment

 check if the given segment index is OK
 To be done (if needed) - cache the lookup table

 returns the sector index
 takes as input the angle, index of the pad row and z position

 returns the default radial position
 of the readout chambers

 Setting the nominal TPC gain slopes
 Nominal values were obtained as a mena values foe 2010,2011, and 2012 data
 Differntial values can be provided per year

  Parameters of the BB for the Aleph parametrization AliMathBase::BetheBlochAleph
  Na49 parameters were used as first set of parameters for ALICE simulation
  (see TPC TDR for details)

  Parameters of the BB for the Aleph parametrization AliMathBase::BetheBlochAleph
  Na49 parameters were used as first set of parameters for ALICE simulation
  Second set was obtained from ALICE 2009-2013 data taking

  GetBetheBloch retur values for the parametrs regieter at poition type
  Used for visualization and comparison purposes

return response bin i  - bin given by  padrow [0] pad[1] timebin[2]

return  weight of response bin i

set cosinus and sinus of rotation angles for sector isec

return rotation angle of given sector

transformation to rotated coordinates
we must have information about sector!
rotate to given sector

transformation to rotated coordinates
we must have information about sector!
rotate to given sector

transformation from  rotated coordinates to global coordinates

transform rotated coordinats of one sector to rotated
coordinates relative to another sector

 asigns the x-position of the closest wire to xyz[0], return the
 electron to closest wire distance

calulates coresponding pad row number, sets index[2] for straight rows
does not change xyz[] information
valid only for straight row

valid only for straight rows straight rows
calculate xyz[0] position relative to given index

valid only for straight rows
transforms  relative xyz[0] to the global one within given sector

transform [x,y,z] to [r,phi,z]

transforms 'digit' coordinates to cylindrical xyz coordinates

ALITPCParam object to be possible change
geometry and some other parameters of TPC
used by AliTPC and AliTPCSector

transform 'digit' coordinata to dr,f coordinata

return pad row of point xyz - xyz is given in coordinate system -(given by index)
output system is 3 for straight row and 7 for cylindrical row

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
transform relative position  to the gloabal position

transform position in digit  units (time slices and pads)  to "normal"
units (cm)
transform position in cm to position in digit unit
