 ** Data class for digital MUCH information
 ** Data level: RAW
 **
 ** The detector ID consists of:
 **   system ID (0-15, STS=2), bits 24-27
 **   station number (0-255), bits 16-23 
 **   sector number (0-32767), bits 1-15
 ** 
 ** The index of the (first) MCPoint having activated this channel
 ** is accessible via GetMcPointIndex().
