Defocus is modeled in Zernike polynomial format as a ( 2 \ rho ^ 2-1 ), where a is the defocus coefficient in wavelengths of light.

The telescope is still in operation after a half century of astronomy at NOFS . It performs key quasar-based degraded seeing ), to higher Zernike polynomials.

Fast algorithms to calculate the forward and inverse Zernike transform use symmetry properties of trigonometric functions, separability of radial and azimuthal parts of Zernike polynomials, and their rotational symmetries.

In each Zernike polynomial Z ^ m _ n, the subscript n is the "'order of aberration "', all the Zernike polynomials in which n = 3 are called third-order aberrations and all the polynomials with n = 4, fourth order aberrations and so on.
