Left: distribution of significances for binary model fits to our calibrators. Right: cumulative distribution of the fitted poisson distribution. We expect no significant asymmetric signal within these stars so use them to form a crude test statistic for our threshold of 4σ. Fitting a poisson distribution we find a confidence level of 88% for a 4σ and more than 95% for 4.5σ.
