Minimum sizes of the dirty beam images to get an image fidelity or a dynamic range greater than a given value.
|or dynamic range||(fb = 0)b||(fb = 0.0625)||(fb = 0.1)|
|105||19.8||> 20.0||> 20.0|
The computation is done for 3 different ratios of the secondary-to-primary diameters (i.e. fb, the antenna blockage factors). The values are derived from the modeling of the antenna power patterns shown in Fig. 3.
