StMuEpdHit::StMuEpdHit

(

StEpdHit *

epdHit

)

constructor based on StEpdHit this is what will be used in constructing the StMuDst from the StEvent

Parameters

epdHit

: the StEpdHit object stored in the StEvent

Definition at line 50 of file StMuEpdHit.cxx.

Member Function Documentation

Short_t StMuEpdHit::id ( ) const

inline

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

Definition at line 127 of file StMuEpdHit.h.

References mId.

Referenced by setId(), and setIdTruth().

Int_t StMuEpdHit::qtData ( )

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 79 of file StMuEpdHit.h.

References mQTdata.

void StMuEpdHit::setId ( Short_t  id )

inline

It is expected that this will not be invoked, but rather the constructor used

Parameters

id	= sign*(100*position+tile) where sign=+/- for West/East wheel

Definition at line 94 of file StMuEpdHit.h.

References id(), and mId.

void StMuEpdHit::SetnMIP ( Float_t  nMIP )

inline

Parameters

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

Definition at line 96 of file StMuEpdHit.h.

References mnMIP, and nMIP().

void StMuEpdHit::setQTdata ( Int_t  packedData )

inline

It is expected that this will not be invoked, but if you want to use it, you have to pack the data yourself. I do not want ability to individually set ADC,TDC,TAC. Better to use the constructor

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 StMuEpdHit::mId

protected

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

Definition at line 109 of file StMuEpdHit.h.

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

Int_t StMuEpdHit::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
