WebJul 16, 2015 · This equation is regularly used by many astronomers (for example Southworth et al. 2009) to estimate the scintillation noise in their measurements. Recent work by Kornilov et al. ( 2012) showed that this equation tends to underestimate the median scintillation noise by a mean factor of 1.5. WebApr 9, 2024 · An alternative approach is to measure the light in the coma using a photometric aperture which is large enough so that it includes the entire coma. For this to be effective it is necessary to accurately estimate the sky background level and to remove the light contributed by the background stars in the photometric aperture.
