The single continuum interface automatically creates four TDM spectral windows located such that they provide maximum sensitivity at low spectral resolution. For 2SB receivers (bands 3, 4, 6, 7 and 8) two spectral windows are placed in each sideband. For bands 9 and 10 (DSB) all four are placed in the same sideband. It is recommended that a receiver band be chosen, as this ensures maximum sensitivity by placing the windows in the centre of the band and avoiding atmospheric absorption features. If necessary, the frequencies of the spectral windows can be changed by setting a different average frequency i.e. the relative positions of the spectral windows is fixed.
The Representative Frequency (Section 5.3.3.6) will default to being the central (sky) frequency of the last spectral window. As with the spectral line interface, this can be changed, both by selecting a different spectral window and by moving the frequency within this. However, it is not possible to change the other parameters of the individual spectral windows.
Spectral averaging is not available for Single Continuum as the spectral resolution is already relatively low.
