Function spherical_radial_sequence 

pub(crate) fn spherical_radial_sequence(
    order: u32,
    z: Complex,
    radial: Radial,
) -> Result<Vec<RadialJet>>

spherical_radial jets of every degree 0..=order at one argument. Regular jets share power-series terms or single AMOS J evaluations. Singular jets share one spherical_hankels sequence, using its positive-real recurrence where qualified and AMOS elsewhere. Against 30-digit values at |Im z| <= 5, the AMOS sequence stays within 2e-13 relative up to order 80 (two-term sequences: 8e-14); below Im z = 0 it loses up to a digit to two-term sequences, still within 1e-13 of each jet’s size up to order 40.
