18.20.3 GUETH

[CLEAN\]MOSAIC GUETH

Select the GUETH mode for imaging. It is based on the Gueth, Guilloteau and Viallefond method. It uses and produces Primary and Dirty beams of the same sizes as the Sky mosaic. A well proven method, somewhat more memory hungry than the SAULT mode, but differences are small for less than 19 fields.
