Thanks, Jakob. I have another doubt.

I find the 'angle'  field in fcd-output is described as--

The angle of the vehicle in navigational standard (0-360 degrees, going
clockwise with 0 at the 12'o clock position)

Is it the angle of the vehicle position with respect to the reference (like
X-axis and Y-axis) or its direction of movement?

I want to find the angle between the vehicles (position) i.e. angle of all
vehicles with respect to one source vehicle. Can I use the angle field? or
do I need to use the position of the vehicles (x,y) to compute such an
angle?

Thanks.
