The so-called generalized spiral points are generated according to [Rakhmanov 1991](http://www.math.vanderbilt.edu/saffeb/texts/155.pdf). * The azimuth and elevation angles are given in closed form * The computation requires the number of microphones....

The monopoles use an expression like `hn(k*rs) * bn(k*r)`, which exist as a limit `k->0` but is undefined for `k==0`. Consequently `spherical_ps` and `circular_ls` yield `NaN` for `k==0`. The DC...
