 ```
 By doing so, the kernel is scalar in the far-field and the computational cost of `m2l`, `l2l` operators is strongly decreased while that of `l2p` increases.
 
+In this case, the far-field kernel has axisymmetries and, to benefit from acceleration in the transfer phase (M2L), the `low_rank_` option must be used and, for a better approximation, the Chebyshev points must be used.
+```c++
+using options = scalfmm::options::chebyshev_<scalfmm::options::low_rank_>;
+```
+This should be the case whenever the far-field kernel depends only on the norm of the distance (r).
