cv.jit.track question

hello!
i've set my cv.jit.track on 4 points
and i can see all of them using cv.jit.track.draw

i need to unpack the data for x/y values
and I can do this for point number one.
Can you point me to how to retrieve the other 3 points data?

May I use jit.matrixinfo
to route the planes information
and then apply to each plane
the cv.jit.track object?

it seems to me there's something wrong...or not working clearly

any suggest appreciated

thank you in advance

tom
