Detailed Description

Converts the TileRawChannel object into bytes.

Amplitude, phase and quality factor are encoded in 16-bit words:

• 14 bits for the amplitude plus 1 bit for the sign and 1 bit for gain,
• 15 bits for the phase plus 1 bit for the sign and
• 15 bits for the quality plus 1 bit for the sign.

getBytes()

int TileRawChannel2Bytes::getBytes	(	const TileFastRawChannel *	rc,
		int	gain,

	)

Pack TileRawChannel information (gain, amplitude, phase and quality) in 3 16-bit words.

Fills in the vector<short> the three entries for the corresponding read-out channel.

Returns number of words added to the vector, 3 for amplitude + phase + quality factor.
