 * **dimension** – 2 or 3 (ignored when not applicable)
-* **length** – linear size of each axis (odd values are adjusted automatically)
+* **length** – 1000
 * **bandlimit** – fractional control variable (0.1 – 0.9 in 0.1 increments for `BandlimitedSignal`, `SparseSphereSignal`, and `Sierpinski`; interpretation varies per class)
 * **seed** – ensures deterministic generation and consistent file paths (for `BandlimitedSignal` and `SparseSphereSignal` the repository ships five predefined seeds: 1234, 2024, 5678, 7890, 7618)
 * **generate** – `True` = create new signal, `False` = load cached `.npy`
