Detailed Description

Converts the TileRawChannel object into bytes as it is defined at the testbeam.

In one 32-bit word:

• 16 bits are used for the energy (non calibrated energy)
• 12 bits are used for the phase (ns)
• 4 bits are used for the quality factor

Member Function Documentation

amplitude()

float TileRawChannel2Bytes2::amplitude ( unsigned int w ) const

inline

Returns the non calibrated amplitude unpacked from the single 32-bit word w.

Definition at line 98 of file TileRawChannel2Bytes2.h.

                                                                  {
  float a = ((w >> AMPLITUDE_SHIFT2) & AMPLITUDE_RANGE2) * (1. / AMPLITUDE_FACTOR2) - AMPLITUDE_OFFSET2;
  if (a < AMPLITUDE_MINVALUE) a += 2 * AMPLITUDE_OFFSET2;
  return a;
}

gain()

int TileRawChannel2Bytes2::gain ( unsigned int w ) const

inline

Returns the gain unpacked from the single 32-bit word w.

Definition at line 93 of file TileRawChannel2Bytes2.h.

                                                           {
  int g = (w >> GAIN_SHIFT2) & GAIN_RANGE2;
  return g;
}

getBytes()

int TileRawChannel2Bytes2::getBytes	(	const TileFastRawChannel *	rc,
		int	gain,
		std::vector< unsigned int > &	v )

Adds an entry to the vector<int> v for this TileRawChannel.

The entry is the single 32-bit word generated using TileRawChannel2Bytes2::getWord() method.

Returns 1 which is the number of entries added to the vector.

Definition at line 10 of file TileRawChannel2Bytes2.cxx.

                                {
  // pack raw data into one 32-bits integer
  v.push_back(getWord(rc, gain));
 
  return 1; // one int added to vector
}

getWord()

unsigned int TileRawChannel2Bytes2::getWord	(	const TileFastRawChannel *	rc,
		int	gain )

Returns a single 32-bit word which encodes the TileRawChannel information (gain,amplitude,phase and quality) for a single read-out channel.
