The default image (prior distribution)


Equation 9 implies that if no data constraints exist, the MEM image is the default image, so the MEM image is always biased towards the default. A reasonable ``default default'' image is flat, with total flux density equal to that specified. A low-resolution image, if available, can be used as the default to good effect; this is a way to combine single-dish data with interferometric data, for example.
