class AliEMCALGeoParams



 class for holding various EMCAL basic parameters
 - number of towers in each dimension per SuperModule
 - info on LED Reference, TRU, Temperature sensors
 and so on.
 Also some simple conversion methods.
 So far it serves as the catch-all to avoid magic numbers inside the code

 This empty cxx file is just added to get the class/numbers into
 the Utils library

Function documentation

Int_t GetStripModule(Int_t iSM, Int_t iCol) const

 Strip 0 is the one closest to the FEE crates; different for A (iColumn/2) and C sides

{ return ( (iSM%2==0) ? iCol/2 : AliEMCALGeoParams::fgkEMCALLEDRefs - 1 - iCol/2 ); }

Int_t GetHWAddress(Int_t iBranch, Int_t iFEC, Int_t iALTRO, Int_t iChannel) const

 RAW/AliCaloAltroMapping provides the correspondence information between
 an electronics HWAddress (Branch<<1 | FEC<<7 | ALTRO<<4 | Channel)
 for the RCUs and which tower (Column and Row) that corresponds to.
 For the cases when one doesn't have a Raw stream to decode the HW address
 into the other FEE indices, we provide the needed simple methods here
 with arguments (within an RCU)

{ return ( (iBranch<<11) | (iFEC<<7) | (iALTRO<<4) | iChannel ); }

Int_t GetBranch(Int_t iHW) const

 and for converting back to the individual indices

{ return ( (iHW>>11) & 0x1 ) ; }

Int_t GetFEC(Int_t iHW) const

{ return ( (iHW>>7) & 0xf ) ; }

Int_t GetAltro(Int_t iHW) const

{ return ( (iHW>>4) & 0x7 ) ; }

Int_t GetChannel(Int_t iHW) const

{ return ( iHW & 0xf ) ; }

Int_t GetCSPAddress(Int_t iBranch, Int_t iFEC, Int_t iCSP) const

 We can also encode a very similar CSP address

{ return ( (iBranch<<11) | (iFEC<<7) | iCSP ); }

Int_t GetCSPFromAddress(Int_t i) const

 and for converting back to the individual indices
 Branch and FEC methods would just be the same as above

{ return ( i & 0x1f ) ; }
