TLinearFitter * AliTPCTempMap::GetLinearFitter	(	Int_t	type,
		Int_t	side,
		UInt_t	timeSec
	)

Creates a TlinearFitter object for the desired region of the TPC (via choosen type and side of TPC temperature sensors) at a given timeSec (in secounds) after start time type: 0 ... ReadOutChambers (ROC) 1 ... OuterContainmentVessel (OFC) 2 ... InnerContainmentVessel (IFC) + ThermalScreener (TS) 3 ... Within the TPC (DriftVolume) (TPC) 4 ... Only InnerContainmentVessel (IFC) side: Can be choosen for type 0 and 3 (otherwise it will be ignored in in order to get all temperature sensors of interest) 0 ... Shaft Side (A) 1 ... Muon Side (C)

Double_t AliTPCTempMap::GetTemperature	(	Double_t	x,
		Double_t	y,
		Double_t	z,
		UInt_t	timeSec
	)

Returns estimated Temperature at given position (x,y,z[cm]) at given time (timeSec) after starttime Method: so far just a linear interpolation between Linar fits of the TPC temperature sensors FIXME: 'Educated Fit' through FiniteElement Simulation results! FIXXME: Return 0? if x,y,z out of range

Double_t AliTPCTempMap::GetTempGradientY	(	UInt_t	timeSec,
		Int_t	side
	)

Extract Linear Vertical Temperature Gradient [K/cm] within the TPC on Shaft Side(A): 0 Muon Side(C): 1 Values based on TemperatureSensors within the TPC ( type: 3 (TPC) )

FIXME: Also return residual-distribution, covariance Matrix or simply chi2 for validity check? -> better use GetLinearFitter - function in this case!
