Parallelized version of class WFCleanImageSkyModel.
Public interface
From "parallel", "wide-field" and "image sky model"
This class is a parallelized version of class WFCleanImageSkyModel, implemented as an inherited specialization. The parallel class uses the same algorithms as the serial parent class, except it is modified to support parallel processing.
See the example for SkyModel.
