WebMar 4, 2024 · FWHM calculation using python. I am trying to calculate the FWHM of spectra using python. The spectral description (I'm talking in terms of the physics) for me it's bit … WebApr 19, 2024 · FWHM is useful to autofocus software, since it needs a way to compare the star sizes after making focuser adjustments. But that's an apples-to-apples comparison of the same stars on the same system, with only the focuser position changing. The actual value doesn't matter. Finding the point where the number is smallest is the important part.

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.
