  COMMENTS                    : Broadband mode
Broadband and narrowband pinging modes are interleaved during
data acquisition.  Both datasets are available for W0502A.  The
broadband (SACID 00863) provides greater resolution in
depth, but less depth penetration.  The narrowband mode (SACID 00864) 
is the opposite.
