 processing Float values using Mean, Median, Standard Deviation wrt Mean, Standar Deviation wrt Median

 parameters[0] = mean
 parameters[1] = truncated mean (calculated excluding points outside +/- 3RMS from mean
 parameters[2] = median
 parameters[3] = standard deviation wrt mean
 parameters[4] = standard deviation wrt median

 processing Float values using Mean, Median, Standard Deviation wrt Mean, Standar Deviation wrt Median
 used for L3 and Dipole magnets, using isZero flag to decide whther the magnet was OFF/ON
 the flag is set according to the L3/Dipole current value
 current threshold for L3 = 350 A (value provided by DCS)
 current threshold for Dipole = 450 A (value provided by DCS)

 parameters[0] = mean
 parameters[1] = truncated mean (calculated excluding points outside +/- 3RMS from mean
 parameters[2] = median
 parameters[3] = standard deviation wrt mean
 parameters[4] = standard deviation wrt median

 processing Boolean values

 processing Int values, returning mean
 AliGRPObject::GetInvalidFloat() is returned if any of the DCS values
 are outside the queried time interval or their value is out of range

 processing Int values, returning mean
 AliGRPObject::GetInvalidFloat() is returned if any of the DCS values

 extract DCS pressure maps. Perform fits to save space

 Retrieves logbook and trigger information from the online logbook
 This information is needed for prompt reconstruction

 Parameters are:
 Run number
 DAQ params: dbHost, dbPort, dbName, user, password, logbookTable, triggerTable
 cdbRoot

 returns:
         positive on success: the return code is the run number of last run processed of the same run type already processed by the SHUTTLE
         0 on success and no run was found
         negative on error

 This function is NOT called during the preprocessor run in the Shuttle!

 Method to process LHC-Clock Phase data
 Only the values between DAQ_time_start and DAQ_time_end are kept

 Method to return the convention for the separate beam type
 in the form A*1000+Z
 e.g.: Pb82 --> 208000 + 82 = 208082
       p --> 1000 + 1 = 1001

 Check file logical records as in TFile::Map()
 returning false in case the position of the final record is bigger than the file size
 It should allow to mark as bad all and only raw tag files which would crash the chaining
