Spurious wings and lesser quills black margined with blue.
"Zoological Illustrations, Volume I" by William Swainson
There are large discrepancies for NBE = 1.2 × 105 , but the disagreement might be spurious because of the strong dependence of the high-mass wings on the numerical resolution.
Numerical and semi-analytic core mass distributions in supersonic isothermal turbulence
The actual resolution attained with a grating is smaller than calculated due to slow variations in the ruling density that can degrade coherence, broaden the wings of the instrumental proﬁle, and produce spurious spectral line and continuum features at the detector [29, 30].
The symbol ∗ marks data points which have been ﬁltered out of a low S/N environment, or from a strong spurious contribution from the HVC emission wings.
Rotation of Jets from Young Stars: New Clues from the Hubble Space Telescope Imaging Spectrograph
To explain why the masked 73 tile data exhibit small non-Gaussian wings, we now consider a second effect that may also lead to spurious claims of non-Gaussian noise.
