\caption{Comparison of the extragalactic and asteroid full
fluctuation power levels at some representative wavelengths of 
infrared and submillimetre space instruments. Asteroid fluctuation power was derived
at the specified $\lambda$$-$$\lambda_{\odot}$ helioecliptic longitude, and
at the ecliptic plane. The columns of the table are: 
1) name of the instrument;
2) wavelength;
3) extragalactic background fluctuation power (EGB);
4) asteroid fluctuation power (MBA);
5) solar elongation used in the MBA fluctuation power calibration, 
in accordance with the visibility constraints of the instrument;
6)~Ecliptic latitude range above/below the ecliptic plane, where a 
specific instrument is considered as "affected'' by asteroid confusion
noise. Missing values indicate that the instrument is \emph{not} affected. }
