Class Description

 for lowtran interface

Double_t Trans(const SinglePhoton& s, const EarthVector& finalpos) const

 Total transmission between photon position and finalpos

 Principle of interpolation from datacard :
    - find a reference transmission (calcuated from ground for reflected -- interpolated within a step for scattered)
    - then get the interaction length and apply it to the real travel

void PreProcess(const BunchOfPhotons& b)

 Preprocessing for bunch transmission along the track (for ckov backscattering simulation)
 Initialization of tables (fAlongTrackCoeff) for a step by step transfer process of a given bunchofphotons

void PreProcessSingles(const Ground* ground, const EarthVector& detector, const ListPhotonsInAtmosphere& track)

 Copy the light track and
 build a transmission map (fToDetectorCoeff), from positions along the track until detector
 used in BunchRadiativeTransfer::PropagationOfSingles()

void Trans(const BunchOfPhotons& b,const EarthVector& nextpos,vector<Double_t*>& coeff) const

 Total transmission between bunch position and a final position
 NB: for a considered bunch, step for running lowtran is independant of step defined for bunch propagation
 (lowtran step is larger.. cf computing time consumption)

Double_t Interpolate(Int_t i,Int_t j,const EarthVector& pos) const

 Interpolate the specified transmission coefficient fAlongTrackCoeff[][i][j]
 to get the value at pos (on the transfer track)

EarthVector InLowtranFrame(const EarthVector& v1,const EarthVector& v2) const

 Change of frame to match lowtran (v1 is the reference vector)
 the frame moves, then v2 expression in the new frame is returned

void CallLowtran100(const EarthVector& pos, const EarthVector& nextpos, LowtranTransferOutput& output) const

 Call lowtran (100 wavelengths processed) to calculate transmission between pos and nextpos, then fill output

Double_t InterpolWl(string type,Double_t w,Double_t w1,Double_t w2,Double_t T1,Double_t T2) const

 Interpolation of transmission coefficients as function of wavelength

void CleanBuffer(string DM)

 Clean the indicated internal trans map (fAlong.. or fToDetect..)

void Reset()

 get ready for next event
