0036 speedOfSoundInWater 4 FLOAT Sound velocity divided by
two in meters/sec loaded
from QMIPS.DAT; specified
with Isis Speed of Sound
command; usually 750.
0040 noLongerUsed 4 FLOAT Was initial sonar signal
divisor in Q-MIPS version
5.19 and earlier. Not
currently used, zeros.
0044 asyncChannelNumber 2 USHORT [0...4] for Q-MIPS, 0 if no
async channel. The async
channel must be the last
(highest number) channel
collected; not used by Isis.
0046 numSonarChannels 2 USHORT [1...4], number of analog
sonar channels being
digitized. In Q-MIPS, divide
sample rate by this number
to get the per-channel
sampling rate.
0048 ch1_processingAvailable 2 USHORT
0050 ch2_processingAvailable 2 USHORT
0052 ch3_processingAvailable 2 USHORT
0054 ch4_processingAvailable 2 USHORT
[0...3], indicates the
presence of, and
processing applied to, each
of the four input channels:
0: not present;
1: raw only;
2: corrected only;
3: both raw and corrected.
