class AliMpDCSNamer: public TObject

 ctor taking the detector name as argument (either trigger or tracker)

 dtor

 Set the detector type
 \param detName = tracker, trigger

 Export the aliases in LDIF format

 Generate a compact list of aliases, for Shuttle test
 This one is completely hand-made, in contrast with GenerateAliases()
 method

 Convert DCS Tracker "slat number" (old convention) to DE (new) convention.

 \param chamberId : chamber number (starting at 0)
 \param side : 0 for Left, 1 for Right
 \param dcsNumber : slat number in DCS convention

 note that dcsNumber should be >=0 and < number of DEs/2 in chamber

 Convert DE to DCS "slat number"
 @see DCS2DE

 Convert a (possibly partial) aliasname to a name (only for MCH)

 Convert a (possibly partial) dcsname to an alias (only for MCH)

 Return the alias name of the DCS Channel for a given DCS area
 \param detElemId
 \param sector = 0,1 or 2 for St12, and is unused for st345 and trigger
 \param dcsMeasure = kDCSHV, kDCSI

 Return the alias name of the DCS Switch for a given PCB
 within a slat of St345

 Converts the dcs alias to a hv index

 dcsAlias has one of the following 3 forms :

 MchHvLv[Left|Right]/Chamber##[Left|Right]/Chamber##[Left|Right]Slat##.actual.vMon

 MchHvLv[Left|Right]/Chamber##[Left|Right]/Chamber##[Left|Right]Quad#Sect#.actual.vMon

 MchDE####dsw#.inValue

 Converts the dcs alias to a detection element identifier

 dcsAlias has one of the following forms :

 MchHvLv[Left|Right]/Chamber##[Left|Right]/Chamber##[Left|Right]Slat##.actual.vMon

 MchHvLv[Left|Right]/Chamber##[Left|Right]/Chamber##[Left|Right]Quad#Sect#.actual.vMon

 MTR_Side[OUTSIDE|INSIDE]_MTChamber##_RPC#_HV.Type[actual.iMon|vEff]

 Get DCS variable from an alias (trigger)

 Generate DCS alias names, for MUON Tracker High Voltage system.
 or for MUON Trigger HV and current system.

 We first generate aliases of DCS channels :

 St 1 ch  1 : 12 channels
      ch  2 : 12 channels
 St 2 ch  3 : 12 channels
      ch  4 : 12 channels
 St 3 ch  5 : 18 channels
      ch  6 : 18 channels
 St 4 ch  7 : 26 channels
      ch  8 : 26 channels
 St 5 ch  9 : 26 channels
      ch 10 : 26 channels

 then aliases of DCS switches (only for St345) : 1 switch per PCB.

 Returns a TObjArray of TObjString(=alias name)

 Convert (de,manu) to hv index, depending on the station

 Returns the index of PCB (within a St345 slat) for a given manu number.
 Returns -1 if (detElemId,manuId) is incorrect

 Return the DCS-sector number (within a St12 quadrant) for a given manu number.

 Returns the number of PCB in a given detection element
 Only works for St345

 Check that the required detElemId either belongs to tracker or trigger
 consistently with the initial definition of the namer

 Below this value we consider tracking HV is off
