A component to simulate an observation

The simulation step can generate a single Visibility or a list of Visibility’s. The parameter keyword determines the way that the list is constructed. If order=’frequency’ then len(frequency) Visibility’s with all times are created. If order=’time’ then len(times) Visibility’s with all frequencies are created. If order = ‘both’ then len(times) * len(times) Visibility’s are created each with a single time and frequency. If order = None then all data are created in one Visibility.

The output format can be either ‘vis’ (for calibration) or ‘vis’ (for imaging)
