Options

There are 2 options you can vary using keyword arguments. All 3 main functions support:

• finesse::Int: {1 ≤ finesse ≤ 100}: multiplicative factor determining the size of the plotted matrix; the total number of elements is capped at 2^20 (~ 1 million) which should avoid aliasing up to ~317 radially and ~499 azimuthally.

Default: 100 (for zernike, proportionally scaled according to the number of polynomials for the wavefront errors).

In creating the plot matrix the step size / length of the variable ranges is automatically chosen such that aliasing is avoided for reasonable orders. The finesse parameter controls how fine the granularity is subsequently at the expense of performance.

Additionally, the wavefront error functions wavefront(ρ, θ, OPD, n_max) and transform(v, ε, δ, ϕ, ω) support:

• precision: number of digits to use after the decimal point in computing the expansion coefficients. Results will be rounded according to this precision and any polynomials with zero-valued coefficients will be ignored when pulling in the Zernike functions while constructing the composite wavefront error; this means lower precision values yield faster results.

Plot options can be set by setting the Zernike.plotconfig fields; see the docstring for more details.
