Thank you so much!

I'm actually still not quite sure what the actual difference is between the streamlines drawn based on absolute velocity and those based on relative velocity.

If the streamlines are drawn based on absolute velocity, they represent the flow field observed from a stationary coordinate system.

If the streamlines are drawn based on relative velocity, they represent the flow field observed from a moving coordinate system. 

I'm not sure if my understanding is correct, haha. It's really difficult to fully grasp the MRF method.
