class AliITSMisAligner: public AliMisAligner

 defaul constructor

 Make the array of alignment objects, depending on the misalignment scenario (Zero, Residual, Full)

 Shift the parameters of the alignment object passed as first argument by the quantities defined by the arguments

 Smear the parameters of the alignment object passed as first argument in the range defined by the subsequent arguments

 Set misalignment for the whole ITS for the standar scenarios (zero, residual, full)
 To make custom misalignments set directly the misalignments at each level (methods "SetS?D*Pars")

 Set misalignment for SPD alignable volumes for the standar scenarios (zero, residual, full)
 To make custom misalignments set directly the misalignments at each level (methods "SetSPD*Pars")

 Set misalignment for SDD alignable volumes for the standar scenarios (zero, residual, full)
 To make custom misalignments set directly the misalignments at each level (methods "SetSDD*Pars")

 Set misalignment for SSD alignable volumes for the standar scenarios (zero, residual, full)
 To make custom misalignments set directly the misalignments at each level (methods "SetSSD*Pars")

 Returns the AliCDBMetaData to be associated with AliCDBEntry which will contain
 the array of alignment objects for ITS misalignment
 Presently "responsible" and "comment" are filled.

 misalignment by symname

 misalignment at the level of sensitive alignable volumes (SPD ladders/ SDD,SSD modules)
 done for all ladders/modules of the given layer

 misalignment at the level of half-staves/ladders (ladd=-1 means that all ladders are scanned)

 misalignment at the level of SPD sectors and half-barrels

 be careful : SPD0 and SPD1 are not physically separated

 symname from layer, ladder, detector

 Get logical names at the level of staves / ladders

 Get logical names at the level of half-staves (SPD) or ladders (SDD and SSD)

 symnane of parent volume

 given the symbolic name set layer and level

 number of volumes on same level

 number of daughter volumes
