Normalized distributions of lo−hi, RR−LL, and trivial closure quantities, as well as lo−hi and trivial closure trace quantities of Sgr A*, NRAO 530, and J1924−2914 from both the (a) CASA and (b) HOPS reduction pipelines. The data from April 6 and 7 have been used for Sgr A*, and for the calibrators we have also used April 11. The distributions prior to (blue) and after (red) accounting for the estimated systematic uncertainties, s, are shown. The values of s for each source and reduction pipeline are given in Table 4. In the top left corner of each distribution, the number of >3σ outliers is given considering thermal noise only, followed by the number of outliers considering thermal plus systematic noise for σ in parentheses. These numbers are followed by the total number of data points after a slash.
