What is the centerline or base for the heading? I found 'heading = 0' is in the direction of the positive y-axis (east). Is this always the case?

Yes, headings in the AV2 MF dataset are consistent across scenarios and defined w.r.t a cartesian coordinate space aligned to cardinal directions.

In other words, a heading of 0 in different scenarios would always map to the same direction in the cartesian coordinate space.
