Velocity
Component
The positive X-axis is
defined perpendicular to
both the probe's stem and
X - Velocity
the axis of the transmit
transducer in the direction
of receiver arm #1 (marked
with a red band).
The positive Y-axis is
defined along the axis of the
transmit transducer from the
Y - Velocity
transmitter towards the
sampling volume (making a
right-handed coordinate
system).
The positive Z-axis is
defined as vertically up in
Z - Velocity
the direction of the probe's
stem.
All Velocities All of the above
e) The continuous lines displayed in the graphics are defined under the following
categories,
i). Thin continuous line represents the one second raw velocity data,
ii). Thick continuous line represents moving average of the one second raw
velocity data.
f) The velocity values displayed in the rectangular boxes for each velocity
component below the graphical display are defined under the following categories,
i). Thin box outline, instantaneous one second raw velocity data,
ii). Thick box outline, represents moving average of the one second raw velocity
data.
