Reference score125,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Instrument design and spectral interpretation could be tied to diffraction-limited separation.

Scientific scope

Exact 1879 XXXI instalment by DOI; other instalments, Airy diffraction and later criteria excluded.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1879 XXXI instalment identified by DOI 10.1080/14786447908639684.
