Results of the completeness tests, comparing the recovered quantities for 10 000 randomly injected three-dimensional-Gaussian sources with sizes typical of the CHIMPS ¹³CO (3–2) sources as a function of the injected peak values. The panels are: fraction of sources recovered (top panel); the median ratio of the recovered to injected peak brightness temperature (middle panel); and the median ratio of the recovered-to-input integrated intensity (bottom panel).
