Fwhm in python
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. WebJul 20, 2024 · The FWHM can then be calculated from the imaginary pixel surface formed by these pixels: surface:=pi *sqr ( r ). r:=sqrt (surface/pi) d:=2*sqrt (surface/pi) star_fwhm:=2*sqrt (pixel_counter/pi) where pixel_counter contains the pixels with a value above 0.5*peak. Personally I don't see a purpose for the FWHM once you have the …
