17. The radial current distribution results in the circular motion of pancake vortices away from the surface (for Josephson vortices surface barrier is not relevant). Besides, such a current distribution excludes the situation with force-free configuration, since the magnetic field cannot be parallel to the driving current in the whole sample. For more detailed discussion related to the Corbino geometry, see Ref. 15.

21. ab phase diagram of the VLMT does not practically depend of the resistance criterion if the resistance level is taken below the kink anomaly. On the other hand, the field of the continuous resistance transition varies strongly with the resistance criterion, and a question concerning how the detected resistivity transition is related to the vortex freezing phase transition near the a-b plane remains still unclear (for more detailed discussion, see Ref. 25).
