## fitscube (BSD 3-Clause)
`fitscube-rs` is a port of the **fitscube** Python package by Alec Thomson — the
image-to-cube combination, frequency/time axis construction (including even vs
uneven spacing detection), per-channel `BEAMS` table handling, bounding-box
trimming, and plane extraction all follow its design and conventions:

The test suite validates `fitscube-rs` output against the upstream `fitscube`
package (installed from PyPI) to confirm parity.
