Figure 9
The best fit residual was obtained for (a) ℓ = 1, (b) ℓ = 2 and (c) ℓ = 3. (d) A plot of the fitting results with valleys representing a minimum in the r.m.s., calculated over the 2D best fit residual image. (e) Fitting results show low r.m.s. values with ℓb within ∼5% error of the expected integer values ℓ. |
