`take_looks` guarded the masked-input path with `arr.mask.ndim == np.ma.nomask`, comparing an int (`ndim`) against the `nomask` sentinel (which is `np.False_`) -- so the branch never behaved as intended. Use the identity check `arr.mask is np.ma.nomask`. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Summary
take_looksguarded its masked-input branch witharr.mask.ndim == np.ma.nomask, which compares an integer (ndim) against thenomasksentinel (np.False_). That comparison is essentially alwaysFalse,so the intended "no mask present" shortcut never triggered.
