Member Function Documentation

short StEpdHit::id ( ) const

inline

unique tile identifier absolulte value is 100*position + tile sign is +1/-1 for West/East

Definition at line 146 of file StEpdHit.h.

References mId.

Referenced by StTpcHitMover::Make(), and setIdTruth().

int StEpdHit::qtData ( ) const

inline

the packed data from the QT board: ADC=bits 0-11; TAC=bits 12-23; TDC=bits 24-28; bit 29=0/1 for has/does not have TAC; bit 30=0/1 if tile is marked bad/good in database

Definition at line 139 of file StEpdHit.h.

References mQTdata.

void StEpdHit::setnMIP ( float nMIP )

inline

Parameters

gain	calibrated energy loss in tile, in units of Landau MPV for one MIP

Definition at line 142 of file StEpdHit.h.

References mnMIP, and nMIP().

void StEpdHit::setQTdata ( int packedData )

inline

This method unlikely to be used frequently. Sets the QT data. You have to bit-pack the data yourself

Parameters

packedData,: ADC=bits 0-11; TAC=bits 12-23; TDC=bits 24-28; bit 29=0/1 for has/does not have TAC; bit 30=0/1 if tile is marked bad/good in database

Member Data Documentation

Short_t StEpdHit::mId

protected

Packed channel Id: abs(mID) = 100*positionId + tileId sign(mID) = +/- = West/East

Definition at line 123 of file StEpdHit.h.

Referenced by id(), position(), side(), and tile().

Int_t StEpdHit::mQTdata

protected

Packed channel data: bits 0-11 are ADC; bits 12-23 are TAC; bits 24-28 are TDC; bit 29 is noTAC flag bit 30 is the good/bad (1/0) status flag

Definition at line 128 of file StEpdHit.h.
