Description

Calculate the relative radius given a zenith angle and lens function. This is known as the projection function.

Usage

calc_relative_radius(angle, lens_coef)

Arguments

angle

Numeric vector. Zenith angles in degrees.

lens_coef

Numeric vector. Polynomial coefficients of the lens projection function. See calibrate_lens().
