Detailed Description

Class helping to decode the MuCTPI multiplicity words.

Date: 2007-09-27 15:22:34

   The multiplicity word(s) in the MuCTPI readout data store the number
   of collected LVL1 muon candidates in 6 p<sub>T</sub> thresholds in (a)
   32-bit word(s). This class can help in decoding such a multiplicity word.

   For a detailed description of the data format of the MuCTPI, see
   the MIROD documentation (https://edms.cern.ch/file/248757/1/mirod.pdf).

Member Function Documentation

◆ dumpData() [1/2]

void MuCTPI_MultiplicityWord_Decoder::dumpData ( ) const

Function dumping the stored information to the message stream.

This function is not responsible for actually printing the information, it just creates a message stream to print the information to with MuCTPI_MultiplicityWord_Decoder::dumpData(MsgStream&) const.

Definition at line 88 of file MuCTPI_MultiplicityWord_Decoder.cxx.

◆ dumpData() [2/2]

void MuCTPI_MultiplicityWord_Decoder::dumpData ( MsgStream & log ) const

Function dumping the stored information to the message stream.

Function printing the decodable information of the MuCTPI multiplicity word in an easy-to-read fashion.

Parameters

log	A message stream to print the information to
