 - `3,5,8`: The frequencies `n_x`, `n_y`, `n_z` used in the parametric equations of the curve, corresponding to the x, y, and z coordinates.
 - `0,pi2,0`: The phase shifts `φ_x`, `φ_y`, `φ_z` in each coordinate. Notation like `pi2` represents fractions of π (e.g., `pi2` = π/2, `pi3` = π/3, etc.).
 - `03_1.1_0.2`: Parameters of the (cosine-based) sinusoidal radius variation for the tubular neighborhood around the curve:
-  - `03`: frequency `f`
-  - `1.1`: constant term `c`
-  - `0.2`: amplitude `a`
+  - `03`: frequency `f`,
+  - `1.1`: constant term `c`,
+  - `0.2`: amplitude `a`,
 
-  Thus, the radius function is:   r(t) = 1.1 + (0.2)cos(3t)
+  from the radius variation function: `r(t) = c ± a·cos(f·t)`, where `t` in `[0,2π)`.
 
 - `r0.02_0.029`: Minimum and maximum radius of the tubular neighborhood.
 - `v90`: Voxel resolution per axis. While v90 nominally refers to a 90 × 90 × 90 voxel grid, an offset of 5 voxels per side was added to prevent surface clipping at the bounding box edges.
