Storage
0020 pingNumber 4 USHORTPing number starts at 1 in each
Q-MIPS file, 0 in each Isis file
and is incremented
automatically. Max = 4.29x10
9
.
0024 asyncByteOffset 2 USHORTWhen non-zero in Q-MIPS,
indicates the presence of a
unique asynchronous ping being
stored with this ping, when 0
indicates the most recent
asynchronous ping (if any) is
being replicated; not used by Isis
0026 shipSpeed 2 USHORTSpeed of ship in knots multiplied

sonar trigger is to be detected,
from QMIPS.DAT.
0050 altSource 2 USHORTAltitude source for water column
removal and correction for slant
range, 0: telemetry, 1-4: water
column detection channel, 5:
manual entry by user, set in
