Number of matched peaks, within 1000 km s⁻¹, above a certain S/N and within of the expected position of HD1. The filled blue and orange circles correspond to the number of positive and negative matched peaks, respectively, in the real data cubes. The solid line, dark- and light shaded regions correspond to the mean, standard deviation and standard error about the mean for the matched pairs of jack-knifed data cubes. We find one matched positive pair in the real data (the tentative [O III] 88 μm and [C II] 158 μm features) at S/N > 3.8. Given the mean and standard deviation on the matched peaks in the jack-knifed data, one set of matched peaks in the real data is perfectly consistent with being noise.
