Spectral Window Tabs

A Spectral Window summary table is visible above the spectral window specification tabs. Apart from a few fields the table also shows the data rates and the sky frequency that can be expected for each spectral window.

Figure 6.19: The Spectral Window forms to provide the Spectral Windows specifications.

The following BL Only subpanel applies to the Baseline Correlator Setup only:

On the right side the Spectral Average Region table is visible that can be used to specify the spectral bands that are to be averaged. The user can select up to 10 sets of contiguous channels (a ChannelAverageRegion) which contribute to the channel average result. Note that these parameters are based on effective channels. That is, Start Channel must be a zero based index within the effective range of spectral channels and the number of channels is interpreted based on the spectral resolution (band-width per channel) before any spectral averaging (spectralAveragingFactor) has been applied.
