WebMar 24, 2024 · Gaussian Function. In one dimension, the Gaussian function is the probability density function of the normal distribution , sometimes also called the frequency curve. The full width at half maximum (FWHM) for a Gaussian is found by finding the half-maximum points . The constant scaling factor can be ignored, so we must solve. http://sobereva.com/g09/k_opt.htm
