Table 1

CPU time requirements for the iterative methods after the calculation of the azimuthal coefficients , Q = 0,1,2.

Method CPU time (s) to compute

Λ A-1 No. of iteration  ×  time/iteration Total

Scattering expansion 0.09 27 15 36  ×  8.13  =  293 335
ALI with core-wing 1.00 62  ×  10.19  =  632 633
ALI with FABFA 1.00 29087 61  ×  27.98  =  1707 30795

Notes. The coefficients are not needed because the model used has ΓER = 0; it is the same as in Figs. 35. The computations are performed on a Sun Fire V20z Server, 2385 MHz, with a Single-core AMD Opteron processor.
