Domain-specific¶
- Hammer Projection
- Aitoff applies the same broad half-longitude-and-horizontal-expansion idea to an azimuthal equidistant kernel, producing a visually similar ellipse without the Hammer equal-area guarantee
This sourceSnyder and Voxland's catalogue, which gives Aitoff and Hammer as adjacent modified-azimuthal entries; the report itself was not available to confirm the exact wording of its Aitoff entry.

- Wiechel Projection
- The Wiechel projection is a spherical, polar, pseudoazimuthal, equal-area map projection presented by H. Wiechel in 1879
This sourceCited for the USGS Album's Usage note, which is what records Wiechel's standing as a novelty rather than an operational map; the 'teaching' characterisation is editorial and is not attested in the sources consulted. The USGS Album entry (p. 149) is the source of the classification and usage characterisation attributed to USGS here; the page itself could not be opened for this check, so the exact three-term classification string remains unconfirmed.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
