WebApr 13, 2024 · Periodograms can be normalized by either Leahy normalization,fractional rms normalization, absolute rms normalization, or not at all. You can also make an empty :class:`Powerspectrum` object to populate withyour own fourier-transformed data (this can sometimes be useful when makingbinned power spectra). WebMar 16, 2015 · Light Curve Analysis. A light curve is the measurement of a celestial body's brightness at certain intervals and over a given period of time (hours, days, months...). Asteroids shine due to the Sun's light reflecting off their surface, and their brightness might vary due to one or more of the following factors: The asteroid's distance to us is ...
