Solar rotation as mesured by Doppler shift method was 7 % slower than that measured by sunspot proper motion technique. This difference my be partly caused by the difference in the measuring techniques, but in general it was believed that this reflects the difference in physical conditions between photospheric (non-magnetic) plasma and sunspots. The movement of sunspots as the tracing still controlled by magnetic field from convective zone, under photosphere layer. Because of that sunspot ratation not exactly to explain the rotation of photosphere layer like Doppler shift method. These physical condition differences will be tray to solve by the total angular momentum derived from Doppler shift method and Tracing method rotation curves.
