2.4.1.0 simulator.setmosaicfield

2.4.1 Set observed mosaic fields
Description

Set mosaic fields by internally invoking setfield multiple times. Currently only handle a rectangular mosaicing pattern. Either setfield or setmosaicfield must be invoked at least once before observe.

If the distance to the object is set then the phase term includes a curvature for the near-field effect at the center of the image.
