Constructor & Destructor Documentation

DTDigi::DTDigi ( int  wire,
int  nTDC,
int  number = 0 
) [explicit]

Construct from the wire#, the TDC counts and the digi number.

number should identify uniquely multiple digis in the same cell.

Definition at line 20 of file DTDigi.cc.

00021   theWire(wire),
00022   theCounts(nTDC),
00023   theNumber(number)
00024 {}

DTDigi::DTDigi ( int  wire,
double  tdrift,
int  number = 0 
) [explicit]

Construct from the wire#, the time (ns) and the digi number.

time is converted in TDC counts (1 TDC = 25./32. ns) number should identify uniquely multiple digis in the same cell.
