Measured α values of R_ℓ14 (left) and R_40ky_ℓ18 (right) at 103 kyr. The disk radius is about 15 AU. The bins for averaging are chosen to be larger than dx in the high-resolution run in order to remove numerical noise. These figures clearly show that the technique of restart using higher resolutions is needed to study the interior properties of the disk. The z components are more important because they dominate in governing the mass accretion inside the disk. The middle layers of the disk are more irregular with some partially expanding parts, while most of the accretion occurs through the upper layer slightly above 3H and reaches a small radius before penetrating the surface of the disk.
