/** PndGemDigi.h
 **@author V.Friese <v.friese@gsi.de>
 **@since 28.08.06
 **@version 1.0
 **
 ** Data class for digital STS information
 ** Data level: RAW
 **
 ** The detector ID consists of:
 **   system ID (0-31, kSTS=2), bits 0-4, see base class
 **   station number (0-255), bits 5-12 
 **   sector number (0-32767), bits 13-27
 **   side (0=front side, 1=back side, bit 28, always 0 for pixel sectors).
 ** 
 ** The index of the (first) MCPoint having activated this channel
 ** is accessible via GetMcPointIndex().
