The shear is proportional to the ellipticity. Other terms used are ellipticity, or oblateness. We now generalize the notion of ellipticity. Lacaille 8760 orbits around the galaxy with a relatively high ellipticity of 0.23. The focus of an ellipse is increasingly off-center with increasing ellipticity. It is not perfectly spherical, but has a projected ellipticity of 0.12. The KSB method measures the ellipticity of a galaxy image. Since formula 8, boundedness and ellipticity of the bilinear form apply to formula 20. Molar ellipticity is circular dichroism corrected for concentration. For a perfect ellipse, the weighted quadrupole moments are related to the weighted ellipticity. The constant depends on the ellipticity of the equation and the connected open region. However, isophotes for this galaxy deviate from a perfect ellipticity, showing pointed shapes instead. However, spooled variable lengths of cable must be used due to ellipticity of the orbits. Note that ellipticity only depends on the highest-order terms. Ellipticity on the laser beam causes the returning electron to miss the parent nucleus.
