Table 5.

Ratio (in percent) of faint interloper contamination (i.e. ‘unmasked faint CO+[CI]’) to the [CII] power amplitude when the latter is evaluated at the mean and at the edges of the [CII] ± 1σ FtF variance interval.

Frequency At +1σ At mean At −1σ Faint interlopers
band /1σ
305 GHz 2% 3% 4% 7%
287 GHz 6% 8% 12% 21%
253 GHz 17% 27% 66% 45%
237 GHz 87% 139% 348% 232%

Notes. The last column gives (also in percent) the ratio between the faint interloper contamination and the 1σ value of the [CII] FtF variance.
