It is usually a plate or strip of metal, or slip of wood, often cut into some fanciful form, and placed upon a perpendicular axis around which it moves freely. "Aye undiscreet, and changing as a vane ."
    • Vane Any flat, extended surface attached to an axis and moved by the wind; as, the vane of a windmill; hence, a similar fixture of any form moved in or by water, air, or other fluid; as, the vane of a screw propeller, a fan blower, an anemometer, etc.

We vowed no more to roam;
From window panes to weather vanes
We loved our floating home.

And they awhile on foremost seat may reign:

As she tied her bonnet under her chin!

In science:

As a result of the E-ELT pupil design, the PSF pattern exhibits strong diffraction effects of the presence of several and large spider vanes.
Design, analysis, and testing of a microdot apodizer for the apodized pupil Lyot coronagraph (Research note). III. Application to extremely large telescopes
Therefore we note that better contrast than the ones presented in our plots are in principle reachable in areas free of the spider vane diffraction residuals.
Design, analysis, and testing of a microdot apodizer for the apodized pupil Lyot coronagraph (Research note). III. Application to extremely large telescopes
The central obscuration is 0.88 mm, while the thickness of the spider vane structures is 0.04 mm. A pupil image (apodized) was recorded using a mini-visible camera, and is shown in Fig. 3 (left).
Design, analysis, and testing of a microdot apodizer for the apodized pupil Lyot coronagraph (Research note). III. Application to extremely large telescopes
The residual energy surrounding the spider vane diffraction residuals (in the form of blue halos) present in both simulated and experimental images was expected.
Design, analysis, and testing of a microdot apodizer for the apodized pupil Lyot coronagraph (Research note). III. Application to extremely large telescopes
In our case, we indeed optimized and designed the apodizer profile with a pupil free of spider vane structures (i.e. only considering the central obscuration ratio).
Design, analysis, and testing of a microdot apodizer for the apodized pupil Lyot coronagraph (Research note). III. Application to extremely large telescopes
This enabled us to neglect the presence of the spider vanes structures, thereby avoiding complex structures in the apodizer with uncertainties related to both manufacturing and practical aspects (e.g. alignment issues).
Design, analysis, and testing of a microdot apodizer for the apodized pupil Lyot coronagraph (Research note). III. Application to extremely large telescopes
Besides, the resulting halo of surrounding light in the vicinity of the spider vanes is mostly masked out by the APLC pupil-stop, enabling good suppression of spider diffraction.

The cycle formed by V (C 1 ) ∪ V (C 2 ) in a M¨obius pinwheel is the ring of the M¨obius pinwheel. A M¨obius pinwheel with 4 vanes contains K6 as a minor as shown on Figure 3.
K_6 minors in 6-connected graphs of bounded tree-width
If l ≥ 4t + 1, then G has a subgraph isomorphic to a subdivision of a pinwheel or a M¨obius pinwheel with t vanes.
K_6 minors in 6-connected graphs of bounded tree-width
Otherwise, we simply construct a pinwheel on t vanes.
K_6 minors in 6-connected graphs of bounded tree-width
As we have seen above a M¨obius pinwheel with sufficiently many vanes contains a K6 minor. A pinwheel is, however, an apex graph.
K_6 minors in 6-connected graphs of bounded tree-width
In order to prove that graphs containing a subdivision of a pinwheel with many vanes satisfy Theorem 1.2, we will need the following lemma concerning subdivisions of apex graphs contained in larger non-apex graphs.
K_6 minors in 6-connected graphs of bounded tree-width
We will show that for every positive integer t every 5-connected non-apex graph G containing a subdivision of a pinwheel with 4t vanes contains a M¨obius pinwheel with t − 1 vanes as a minor. A M¨obius pinwheel with 4 vanes contains a K6 minor, as observed above, and so the lemma will follow.
K_6 minors in 6-connected graphs of bounded tree-width
Let H be the pinwheel with 4t vanes, and let v be the “hub” of the pinwheel (denoted by x in the definition of a pinwheel).
K_6 minors in 6-connected graphs of bounded tree-width
If is easy to see that the resulting graph contains a subdivision of a M¨obius pinwheel with t − 1 vanes, as claimed. (cid:3) The next corollary follows immediately from Lemmas 5.1 and 5.3.
