Figure 3: Latitudinal variation of the tachocline thickness for the case in Fig. 2. The solid line represents the thickness from the model and the dashed and dashed-dot lines show w from MDI and GONG data respectively (Basu & Antia 2001). The grey and the hatched areas show the error estimates on these. |
