... photometry noise as a combination of a central Gaussian peak and exponential tails and suggest that the Gaussian part comes from standard photon counting statistics (Poisson in the high counts limit) and the tails from ?other effects?, possibly crowding ...
... in the two bands. compute HR=(H-S)/(H+S) , sort it, and pick out the appropriate rows to get the equal-tail error range ... sort -n | head -125 | tail -1 | awk '{print $1/1e5}' cat output_draws.txt | awk '{print ($2-$1)/($2+$1)*1e5}' | sort -n | ...
... For example, when modeling luminosities, the use of fatter tailed distribution (say, a power law or even a log-normal) often serves to make inferences more robust to than inclusion of very bright sources than traditional least-squares methods. ...
... a setting in which we test whether each of n tests is truly Gaussian, or a superposition of a Gaussian component with a very faint nonGaussian component, whose distribution is unknown but symmetric and has a power-law tail, e.g. the tail probability |x ...
