 * \brief Hadron and Muon monitor data.
 *
 * Provide routines specific to hadron and muon monitors for unpacking
 * the data based on channel or pixel numbers.
 *
 * The hadron monitor channel mapping is different (transposed) from
 * the muon monitors mapping.  Both count pixels starting from row=1
 * and col=1 with the origin at the lower left.  See NuMI-B-1084 for
 * diagrams.
